In some languages, verb tenses are not very important or do not even exist. In English, the concept of tense is very important.
In this lesson we look at the idea behind tense, how to avoid confusing tense with time, and the structure of the basic tenses, with examples using a regular verb, an irregular verb and the verb be.
- What is Tense?
- Tense & Time
- Basic Tenses
- Be
tense (noun): a form of a verb used to indicate the time, and sometimes the continuation or completeness, of an action in relation to the time of speaking. (From Latin tempus = time).
Tense is a method that we use in English to refer to time - past, present and future. Many languages use tenses to talk about time. Other languages have no tenses, but of course they can still talk about time, using different methods.
So, we talk about time in English with tenses. But, and this is a very big but:
- we can also talk about time without using tenses (for example, going to is a special construction to talk about the future, it is not a tense)
- one tense does not always talk about one time (see Tense & Time for more about this)
Here are some of the terms used in discussing verbs and tenses.
Mood
indicative mood expresses a simple statement of fact, which can be positive (affirmative) or negative
- I like coffee.
- I do not like coffee.
interrogative mood expresses a question
- Why do you like coffee?
imperative mood expresses a command
- Sit down!
subjunctive mood expresses what is imagined or wished or possible
- The President ordered that he attend the meeting.
Voice
Voice shows the relationship of the subject to the action. In the active voice, the subject does the action (cats eat mice). In the passive voice, the subject receives the action (mice are eaten by cats). Among other things, we can use voice to help us change the focus of attention.
Aspect
Aspect expresses a feature of the action related to time, such as completion or duration. Present simple and past simple tenses have no aspect, but if we wish we can stress with other tenses that:
- the action or state referred to by the verb is completed (and often still relevant), for example:
I have emailed the report to Jane. (so now she has the report)
(This is called perfective aspect, using perfect tenses.) - the action or state referred to by the verb is in progress or continuing (that is, uncompleted), for example:
We are eating.
(This is called progressive aspect, using progressive [continuous] tenses.)
Tense and Time
It is important not to confuse the name of a verb tense with the way we use it to talk about time.
For example, a present tense does not always refer to present time:
- I hope it rains tomorrow.
"rains" is present simple, but it refers here to future time (tomorrow)
Or a past tense does not always refer to past time:
- If I had some money now, I could buy it.
"had" is past simple but it refers here to present time (now)
The following examples show how different tenses can be used to talk about different times.

| ||||||
Future Perfect Simple
|
I will have finished by 9pm tonight.
| ||||||
We will have been married for ten years next month.
| |||||||
Future Perfect Continuous
|

| ||||||

*Some grammar books use the word progressive instead of continuous. They are exactly the same.
Basic Tenses
For past and present, there are 2 simple tenses + 6 complex tenses (using auxiliary verbs). To these, we can add 4 "modal tenses" for the future (using modal auxiliary verbs will/shall). This makes a total of 12 tenses in the active voice. Another 12 tenses are available in the passive voice. So now we have 24 tenses.

The use of tenses in English may be quite complicated, but the structure of English tenses is actually very simple. The basic structure for a positive sentence is:
subject + auxiliary verb + main verb
An auxiliary verb is used in all tenses. (In the simple present and simple past tenses, the auxiliary verb is usually suppressed for the affirmative, but it does exist for intensification.) The following table shows the 12 tenses for the verb to work in the active voice.

* Technically, there are no future tenses in English. The word will is a modal auxiliary verb and future tenses are sometimes called "modal tenses". The examples are included here for convenience and comparison.
Basic Tenses: Regular Verb
This page shows the basic tenses with the regular verb work. It includes the affirmative or positive form (+), the negative form (-) and the interrogative or question form (?).
The basic structure is:
positive:
|
+
|
subject + auxiliary verb + main verb
| |
negative:
|
-
|
subject + auxiliary verb + not + main verb
| |
question:
|
?
|
auxiliary verb + subject + main verb
|
These are the forms of the main verb that we use to construct the tenses:
base verb
|

|
present participle -ing

|

Basic Tenses: Be
This page shows the basic tenses with the verb be. It includes the affirmative or positive form (+), the negative form (-) and the interrogative or question form (?).
The basic structure is:
positive (+):
|
subject + auxiliary verb + main verb
|
negative (-):
|
subject + auxiliary verb + not + main verb
|
question (?):
|
auxiliary verb + subject + main verb
|
But for simple past and simple present tenses, the structure is not the same. In fact, it's even easier. There is no auxiliary verb. Here is the structure:
positive (+):
|
subject + main verb
|
negative (-):
|
subject + main verb + not
|
question (?):
|
main verb + subject
|
These are the forms of the main verb be that we use to construct the tenses:

was, were
