English Tenses: Structures, Signal Words and Uses to Understand Clearly English tenses are an area of grammar where many students lose marks, even after learning plenty of structures. The cause usually isn’t remembering a structure wrongly; it’s not yet understanding when to use each tense in real contexts. This article sets out all 12 English tenses, how to tell apart the pairs that are easily confused, common mistakes and suggestions for parents supporting their child. What are English tenses? English tenses are a grammatical system that helps learners express the time, state and degree of completion of an action. Put simply, a tense shows whether an action is happening, has happened, will happen or has been completed at a particular point in time. For Vietnamese students, this area is often difficult because Vietnamese doesn’t conjugate verbs as clearly as English does. In a sentence such as “con học tiếng Anh” (“I study English”), Vietnamese speakers can work out the meaning from context. In English, however, learners must choose the right tense for the sentence to be clear. The 12 basic English tenses and why they need to be used appropriately in speaking and writing Why does English need tenses? English needs tenses because each tense expresses a different shade of time. If a tense is used incorrectly, the listener may misunderstand when an action took place or what state it is in. A tense in English usually answers three questions: Does the action happen in the present, past or future? Is the action in progress or has it finished? Is the action still connected to the present? For example, daily habits usually take the present simple. An action happening at the moment of speaking takes the present continuous. An experience that has happened but is still connected to the present usually takes the present perfect. That’s why learning English tenses shouldn’t start with structures alone. Students need to understand the context first, then memorise how to conjugate the verb. How many tenses are there in English? Learners are usually introduced to 12 English tenses. These tenses are divided into three main time groups: Present tenses Past tenses Future tenses Within each group, the tenses are divided into four forms: Simple: expresses facts, habits or main actions. Continuous: emphasises an action in progress. Perfect: emphasises a result or completion. Perfect continuous: emphasises a process that lasts over time. This way of grouping helps students see the structures of English tenses as a clear system. When children understand the timeline, they can more easily see why the same action is conjugated differently. Do children need to learn all 12 tenses from the start? Not necessarily. For beginners, especially young students, learning all 12 tenses at once can easily be overwhelming. Children should start with the tenses that appear most often in everyday conversation and lessons. A sensible learning order might be: Present simple Present continuous Past simple Future simple Present perfect The remaining advanced tenses This approach helps children use English in real sentences, rather than only getting verb conjugation exercises right. Once they are familiar with the contexts, moving on to more complex tenses becomes easier and longer-lasting. This is also how children learn language in a multilingual environment at an international school, where English is used every day to communicate and to learn other subjects. Summary table of the 12 English tenses When learning English tenses, many students begin by memorising structures. This may help with exercises in the short term, but it easily leads to confusion when speaking or writing. Children need to see the 12 English tenses along a timeline: present, past and future. The table below helps students quickly grasp the name of each tense, its structure, its main use and common signal words. Quick summary table of the 12 tenses Time group Tense Basic structure Main use Common signal words Present Present simple S + V(s/es) Habits, facts, timetables always, usually, every day Present Present continuous S + am/is/are + V-ing An action in progress now, at the moment Present Present perfect S + have/has + V3/ed Experiences, results connected to the present since, for, already, yet Present Present perfect continuous S + have/has been + V-ing An action lasting up to the present since, for, all day Past Past simple S + V2/ed A finished action yesterday, last week, ago Past Past continuous S + was/were + V-ing An action in progress in the past while, when Past Past perfect S + had + V3/ed An action that happened before a point in the past before, after, by the time Past Past perfect continuous S + had been + V-ing Emphasises a process before a point in the past for, since, before Future Future simple S + will + V Predictions, instant decisions tomorrow, next week Future Future continuous S + will be + V-ing An action in progress at a point in the future at this time tomorrow Future Future perfect S + will have + V3/ed Completion before a point in the future by, by the time Future Future perfect continuous S + will have been + V-ing Emphasises a process lasting up to a point in the future for, by then Seeing the 12 tenses on a timeline The easiest way to understand tenses is not to learn each one as a separate structure. Students should ask themselves: does the action happen in the present, past or future? Is it a habit, in progress, completed or ongoing over time? For example, “I do my homework” describes a habit. “I am doing my homework” describes something being done right now. “I have done my homework” emphasises that the homework is finished and the result is still relevant now. Once children understand this logic, learning tenses becomes easier. Structures are still important, but they should only come after children understand the context of use. A timeline helps students see the 12 tenses through Past – Present – Future logic instead of learning each structure separately Present tenses in English Among the 12 English tenses, the present group is the foundation students need to grasp early. These tenses appear frequently in everyday conversation, personal writing, presentations and learning activities in English. When learning this group, students shouldn’t just memorise the structures. What matters is understanding the state of the action: repeated regularly, in progress, completed or continuing up to the present. Present simple The present simple is used to talk about habits, fixed timetables, preferences or general truths. It is the most basic tense in the present group. Structure: Sentence type With ordinary verbs With the verb "to be" Affirmative S + V / V(s/es) + O S + to be + N/Adj Negative S + don't/doesn't + V (inf) + O S + to be + not + N/Adj Interrogative (Wh- question +) Do/Does + S + V + O? (Wh- question +) To be + S + N/Adj? Example: She reads English books every evening. Signal words: always, often, usually, seldom, sometimes, hardly ever every day / every month / every year / every week… once / twice / three times / four times + a period of time, e.g. once a day / a week / a month… A common mistake is forgetting to add “s/es” to the verb when the subject is he, she or it. A simple tip: if an action is repeated regularly, think of the present simple first. Present continuous The present continuous is used to describe an action happening at the moment of speaking. It is also used for near-future plans that have already been arranged. Structure: Sentence type Structure Affirmative S + am/is/are + V-ing + O Negative S + am/is/are + not + V-ing + O Interrogative (Wh- question +) Am/Is/Are + S + V-ing + O? Example: He is working on his science project now. Signal words: Time adverbs: now, at present, at the moment, right now, it’s + time + now Verbs used as suggestions or commands: Look!, Listen!, Watch out!, Keep silent! A common mistake is leaving out the verb “to be”. For example, “She studying” is incorrect. The correct sentence is “She is studying”. When an action is happening right in front of them, students should go for the present continuous. Present perfect The present perfect is used to talk about experiences, results that have just been completed, or actions that started in the past but are still connected to the present. Structure: Sentence type Structure Affirmative S + have/has + V3/V-ed + O Negative S + have/has not + V3/V-ed + O Interrogative (Wh- question +) Have/Has + S + V3/V-ed + O? Example: I have finished my English homework. Signal words: for a long time, for 2 years since 2000, since 1975 just already before yet ever / never recently / in recent years / lately until now / up to now / so far The pair most easily confused is the present perfect and the past simple. If the sentence emphasises a result still connected to the present, use the present perfect. If there is a finished time reference such as yesterday or last week, the past simple is usually used. Present perfect continuous The present perfect continuous emphasises a process that has lasted from the past up to the present. It is usually used when the speaker wants to make the continuity of an action clear. Structure: Sentence type Structure Affirmative S + have/has been + V-ing + O Negative S + have/has not been + V-ing + O Interrogative (Wh- question +) Have/Has + S + been + V-ing + O? Example: She has been learning English for three years. Signal words: for a long time, for 2 years since 2000, since 1975 all day long all morning / all afternoon all her / his lifetime How long…? Past tenses in English Among the 12 English tenses, the past group helps students recount events that have happened, describe settings and put actions in order. These tenses often appear in storytelling, talks about personal experiences and short academic writing. Past simple The past simple is used to talk about an action that happened and finished in the past. Learners usually use this tense when there is a clear time reference such as yesterday, last week or a specific year. Structure: Sentence type Structure Affirmative S + V2/V-ed + O Negative S + did not + V (base form) + O Interrogative (Wh- question +) Did + S + V (base form) + O? Examples: I visited my grandparents last weekend. She did not finish her homework yesterday. Did you watch the film last night? Signal words: yesterday in the past the day before ago last week / year / month this morning, this afternoon Past continuous The past continuous is used to describe an action in progress at a point in the past. It is also used to set the scene for another action that interrupts it. Structure: Sentence type Structure Affirmative S + was/were + V-ing + O Negative S + was/were + not + V-ing + O Interrogative (Wh- question +) Was/Were + S + V-ing + O? Examples: I was reading at 8 p.m. yesterday. They were not playing outside when it rained. Were you studying when I called? Signal words: at 8 p.m. yesterday… at this time last week, at this moment last month… in + a year in the past in the past when, to describe an action that interrupts while, to talk about actions happening at the same time Past perfect The past perfect is used when there are two actions in the past. The action that happened first takes the past perfect, while the action that happened later usually takes the past simple. Structure: Sentence type Structure Affirmative S + had + V3/V-ed + O Negative S + had not + V3/V-ed + O Interrogative (Wh- question +) Had + S + V3/V-ed + O? Examples: The class had started before I arrived. She had not eaten breakfast before school. Had you finished the project before the deadline? Signal words: until then, prior to that time, as soon as, by… before, after, when by the time + S + V by the end of + a time in the past Past perfect continuous The past perfect continuous emphasises an action that continued up to a point in the past. It is usually used to highlight the process, not just the result. Structure: Sentence type Structure Affirmative S + had been + V-ing Negative S + had not been + V-ing Interrogative (Wh- question +) Had + S + been + V-ing? Examples: She had been studying for two hours before the test began. They had not been waiting long before the bus arrived. Had he been practising before the competition? Signal words: since, for, how long until then by the time prior to that time before, after Future tenses in English The future group is used to talk about plans, predictions, promises or actions that will happen after the present moment. When learning English tenses, students should clearly distinguish how certain an action is. This helps them avoid using “will” for every future situation. Future simple The future simple is usually used for decisions made at the moment of speaking, uncertain predictions, promises or offers. It is the most basic tense in the future group. Structure: Sentence type Structure Affirmative S + shall/will + V + O Negative S + shall/will not (won't) + V + O Interrogative (Wh- question +) Shall/Will + S + V + O? Examples: I will call you after school. She will probably join the English club next term. Will you help me with this exercise? Signal words: tomorrow next day / week / month / year someday soon probably as soon as I think / suppose / believe I promise Future continuous The future continuous is used to express an action that will be in progress at a specific point in the future. It often appears when talking about schedules, study plans or activities that have been pictured in advance. Structure: Sentence type Structure Affirmative S + will be + V-ing + O Negative S + will not (won't) be + V-ing + O Interrogative (Wh- question +) Will/Won't + S + be + V-ing + O? Examples: At 8 p.m. tomorrow, I will be doing my homework. This time next week, she will be preparing for her presentation. Will you be studying English at this time tomorrow? Signal words: at this time tomorrow at 8 p.m. next Monday this time next week while when in the future Future perfect The future perfect is used to say that an action will be completed before a point in the future. When learning the structures of English tenses, students should pay attention to the word “by” in this tense. Structure: Sentence type Structure Affirmative S + will have + V3/ed + O Negative S + will not (won't) have + V3/ed + O Interrogative (Wh- question +) Will + S + have + V3/ed + O? Examples: By Friday, I will have finished my English essay. She will have completed the project before the deadline. Will they have submitted the assignment by tomorrow? Signal words: by by the time before by tomorrow by next week by the end of this month at + a point in the future when + a clause in the present simple Future perfect continuous The future perfect continuous emphasises how long an action will have lasted up to a point in the future. It is an advanced tense and is used less in basic conversation. Structure: Sentence type Structure Affirmative S + will have been + V-ing + O Negative S + will not (won't) have been + V-ing + O Interrogative (Wh- question +) Will + S + have been + V-ing + O? Examples: By next month, she will have been learning English for five years. By 2027, they will have been studying at this school for three years. Will you have been preparing for the exam for two months by then? Signal words: for + a period of time + by by next month / year by the time how long until then before + a point in the future Easily confused English tenses and how to tell them apart While learning the 12 English tenses, many students don’t make mistakes because they forget the structures. They usually make mistakes because they don’t yet understand the context of use. Two sentences may mean the same thing in Vietnamese, yet need two different tenses in English. So when learning the structures of English tenses, learners shouldn’t just memorise them. They need to pay attention to three factors: when the action happens, whether it has finished, and whether the speaker wants to emphasise the result or the process. A comparison of 4 easily confused pairs of English tenses, with examples and how to tell them apart Present simple vs present continuous The present simple is used to talk about habits, fixed schedules or general truths. The present continuous is used for an action happening at the moment of speaking, or a situation that is only temporary. Examples: I study English every Monday.→ A fixed timetable. I am studying English now.→ Something happening right now. How to tell them apart: Look at how stable the action is. If it is repeated regularly, use the present simple. If it is in progress or only happens for a short period, use the present continuous. Past simple vs present perfect The past simple is used when an action has finished and there is a clear time reference in the past. The present perfect is used when an action happened before now, but its result or the experience is still connected to the present. Examples: I finished my homework last night.→ There is a time reference, “last night”, so the past simple is used. I have finished my homework.→ Emphasises the result: the homework is done. How to tell them apart: When you see time references such as yesterday, last week or in 2020, you usually need the past simple. When you want to talk about an experience, a present result or a period lasting up to now, the present perfect is more suitable. Will vs be going to Will is usually used for decisions made at the moment of speaking, promises, offers or predictions without clear evidence. Be going to is used for plans made in advance, or predictions based on signs you can see. Examples: “I will help you”→ Shows a decision that has just been made. “I am going to visit my grandparents this weekend”→ Shows a plan prepared in advance. How to tell them apart: Learners can simply remember that will leans towards an instant reaction, while be going to leans towards a plan or clear evidence. Present perfect vs present perfect continuous The present perfect usually emphasises the result of an action. The present perfect continuous emphasises how long the action has been going on. Example: “I have read this book” tells us the speaker has finished the book. “I have been reading this book for two hours” emphasises that the reading has lasted two hours and may still be going on. How to tell them apart: This pair is easily confused because both are connected to the present. When you want to emphasise “what has been done”, use the present perfect. When you want to emphasise “how long it has been going on”, use the present perfect continuous. Common mistakes when learning English tenses Many students don’t make mistakes because they don’t know the structures, but because they don’t yet understand how to choose a tense in each context. When learning the 12 English tenses, if children only memorise the table of structures, they can easily get individual exercises right but struggle when speaking or writing a paragraph. Memorising structures without understanding context This is the most common mistake. Students may remember the structures of English tenses but not know whether the action being described has finished, is in progress or is still connected to the present. For example, “I did my homework” and “I have done my homework” both talk about doing homework. However, the second sentence focuses on the present result: the homework is done. Without understanding this, children will choose a tense based on gut feeling. Over-relying on signal words Words such as “yesterday”, “now”, “since” and “for” are very useful, but signal words aren’t always enough to choose a tense. Some students see “now” and immediately use the present continuous. In complex sentences, however, “now” may simply indicate the present context, not necessarily an action in progress. That’s why children need to read the whole sentence, not just pick out one keyword. Translating word for word from Vietnamese into English Vietnamese doesn’t conjugate verbs as clearly as English does. As a result, word-for-word translation can easily make students overlook the time and state of an action. Instead of asking “how do you translate this sentence?”, children should ask themselves: when did this happen, has it finished, and is it still connected to the present? Asking these questions helps them use tenses more accurately. Not practising tenses through speaking and writing If children only do verb conjugation exercises, they will find it hard to use tenses naturally. Grammar needs to be practised in spoken sentences, written paragraphs and real situations. Parents can start very simply: ask your child to say three sentences about today, three sentences about yesterday and three sentences about their weekend plans. This helps them move from “remembering structures” to “being able to use them in conversation”. 4 common mistakes when learning tenses and how to help your child avoid them when communicating Effective ways to learn English tenses for students and parents Once students know the English tenses, they shouldn’t just go back to memorising the table of structures. What matters more is understanding what kind of action each tense describes. Is the action in progress, finished, lasting up to the present or going to happen in the future? Learning this way, the structures of English tenses are no longer dry grammar. Children will find it easier to use tenses when speaking, writing and reading. Learn along a timeline rather than structure by structure A common mistake is learning each tense as a separate structure. This easily leads children to remember one and forget another, especially when they come across tenses that are similar. Parents can help their child draw a simple timeline: Past: things that happened or have finished Present: habits, facts, things in progress Future: intentions, plans or predictions Then place each tense in the right group. For example, the past simple belongs with finished events. The present perfect sits between the past and the present, because the action started earlier but is still connected to now. This way of learning helps children understand the logic of tenses. They don’t just remember “signal words”; they know why they need to use that tense. Use real-life examples The closer examples are to a child’s life, the better they remember them. Instead of only asking your child to conjugate verbs in isolated sentences, you can use familiar situations. Some easy-to-use examples: Weekly timetable: “I go to school from Monday to Friday.” Something in progress: “I am doing my homework.” An experience: “I have joined a science project.” Weekend plans: “I am going to visit my grandparents.” These sentences help children understand tenses in real contexts. When they come across a similar situation, they will find it easier to recall how to use them. Children pick up tense structures more naturally when English is used in everyday classroom activities How should parents support their child? Parents don’t need to re-teach all 12 English tenses. The more important role is helping your child identify the context before choosing a tense. You can ask your child short questions such as: When did this happen? Has it finished yet? Is it still connected to the present? Is this a habit or something in progress? Is this a firm plan or a decision just made? If your child uses the wrong tense, don’t just correct the answer. Ask why they chose that tense. Their answer will show whether they are confused about the structure, the signal words or the underlying sense of time. If you want to go further, you can explore methods for teaching bilingual children at home to build natural English habits into everyday life. Observe how your child uses tenses, not just their marks Test scores don’t fully reflect a child’s ability to use tenses. A student may get verb conjugation exercises right but still struggle to recount something that has happened. Parents should also observe through small activities: Recounting a school day in English Writing 3–5 diary sentences each week Talking about weekend plans Describing a past experience Reading a short passage and identifying the tenses in each sentence Only when children use tenses correctly in real contexts does grammar become a usable skill. This is a more important goal than memorising the whole table of structures as quickly as possible. English tenses shouldn’t be learnt as a list of structures to memorise. When students understand the timeline and the context of use, they will know why each action needs a different tense. What matters isn’t memorising all 12 English tenses quickly, but using them correctly in conversation, writing and everyday learning. A lasting way to learn is to start with the most basic tenses, practise through real situations and let grammar become a natural, usable skill. This is also the spirit running through the IB and Bilingual learning pathways at Westlink, where children acquire language through experience rather than rote learning.
