Verb Tenses


Unfortunately, this is a trick question, because the term "tense" as it's used in the discussion of verbs has a specific meaning and a general one.

Technically speaking, "tense" specifically refers to the way that time inflects the verb's action:  past, present, and future.

However, "tense" is commonly used instead of the word "conjugation." "Conjugate" means, "to join together," and verbs are actually grouped together by virtue of sharing a sense of duration, condition and/or mood.  Within most of those groupings, specific tense of time—past, present and future—can be added.

The answer to the question above, then, depends on whether you mean this specific idea of tense, or the general idea of conjugation.  For the purposes of this lesson, though, "tense" will be used in the most general sense to discuss conjugation and the elements of time and duration, all together.


Choosing the right verb tense depends upon two factors: time and duration.

"Time" refers to when an action occurs: in the present; in the past; or, in the future.

"Duration" refers to how an action is perceived: as completed; in progress; or, as a recurrent phenomenon or habit.

Time and duration, together, create six different "coordinates," and the different combinations of these coordinates create the variety in verb tense (that is, the different verb conjugations). Some combinations are simple and straightforward, while other combinations create subtle distinctions.

Special conditions and moods can also add other factors to the equation (for example, "fantasy versus reality"). Every writer needs to master these distinctions in order to write clearly and to avoid grammatical errors. The four main verb tenses are:

Continuous (a.k.a. Progressive)
Continuous Perfect


The simple verb tense is the most straightforward and obvious conveyance of action because it does not factor duration; it describes simple occurrence. The simple present tense, however, can be used to suggest a tendency or habit (we live; we breathe; we eat; we work; etc.) Because it does not factor duration, simple present tense uses no specially auxiliary verb other than what's needed to indicate time.

Simple Present

What occurs?
[base verb form]

I record my thoughts in my journal each day.

Simple Future

What will occur? / What's going to occur?
1. informal [am / is / are] + [going to] + [verb]*;
2. formal [will] + [verb]

This verb tense suggests an action that is ongoing or in progress, whether in the now, in the past, or in the future; it uses the auxiliary verb "be" and a present participle form of the verb.

Continuous Present

Continuous Future

What will be occurring? / What's going to be occurring?
[will / is going to] + [be] + [verb + ing]

We're going to be traveling in Croatia this summer.
Food prices in the coming years will be slowly increasing because of this year's drought.


The perfect tense suggests an action completed (i.e., perfected), whether in the now, in the past, or in the future; it uses the auxiliary verb "have" and a past participle form of the verb.

Perfect Present

What has occurred until now?
[has / have] + [past participle]

I have completed the first draft of the assignment.

This company has staked its reputation on its customer service.

Perfect Past

[had] + [past participle]

This year, autumn ended just as mild as it had begun.
Why had you even bothered inviting them to the wedding?

Perfect Future

What is going to have occurred when time's up?
[will / is going to] + [have] + [past participle]

When I finish, I will have proven myself to all those who said I couldn't do it.
I fantasize that, in ten years time, I'm going to have won the lottery, traveled the world, and cured cancer.

Perfect Continuous

The perfect continuous tense suggests a continuous action completed (i.e., perfected), up until now, up to a time in the past, or up until a time in the future; it uses the auxiliary verb "have been" and a present participle form of the verb.

Perfect Continuous Present

What has been occurring till now?
[has / have] + [been] + [verb + ing]

A Note About “Going To” (The Informal Future Helping Verb)

In the interest of total transparency, you should understand why the informal future tense auxiliary verb phrase, “is going to,” is inappropriate for formal writing. Note how “going” ends with “-ing,” which means this is actually in the progressive “continuous” tense. (See below.) “Going to” suggests an intention or destination, which is perhaps why it is associated with the idea of “future.” Nevertheless, for the strict demands of academic and formal writing, “going to” is far too grammatically sloppy in anything but the progressive tenses, which is why you should instead strive to use the auxiliary verb “will” when you are writing formal or academic prose.

The other concern about “going to” is purely rhetorical: “will” can sometimes express intentionality more forcefully, while “going to” connotes straightforward observation. Note the difference in the following examples:

Harriet is going to take a leave of absence at the end of the week.
Harriet will take a leave of absence at the end of the week.

In the first sentence, “is going to take a leave of absence” sounds as if it's an “FYI” remark: “Hey, everyone, just so you know, Harriet's going to be gone next week.” The second example, however, draws focus to Harriet's intention to take a leave of absence and invites a more serious response, including questions about Harriet's motives: “Attention, everyone: Harriet must take a leave of absence at the end of this week, owing to urgent circumstances.” (If we were living in the last century, we might have used the modal "shall" to achieve the same effect of intention or resolve, but, alas, in the twenty-first century, "shall" and its charming contraction, "shalln't," are only ever heard in period performance works like Downton Abbey or Jane Austin adaptations. Pity!)

Because “will” and “go” are ordinary verbs, too, you might also wish to choose one auxiliary form over the other to avoid the appearance of repetition in a verb string:

He [is going to be going / will be going] to a conference this summer.
If I have to, I [will will / am going to will] myself to stay up all night and finish this project.
