In grammar, the word tense refers to the time period in which the verb of a sentence places an
action. There are two tenses in English: present and past. Unlike many languages, English does
not have a future tense. To talk about the future, English requires either the modal verb WILL or
the present progressive.
Aspects
SIMPLE: The simple present (also called present indefinite) is a verb tense which is
used to show repetition, habit or generalization. Less commonly, the simple present
can be used to talk about scheduled actions in the near future and, in some cases,
actions happening now.
PERFECT: The present perfect is a verb tense which is used to show that
an action has taken place once or many times before now. The present
perfect is most frequently used to talk about experiences or changes
that have taken place, but there are other less common uses as well.
CONTINOUS: The present continuous (also called present progressive) is a verb tense which is used to show
that an ongoing action is happening now, either at the moment of speech or now in a larger sense. The
present continuous can also be used to show that an action is going to take place in the near future.
The present continuous is formed using am/is/are + present participle. Questions are indicated by
inverting the subject and am/is/are. Negatives are made with not.
The present perfect is formed using has/have + past participle. Questions are indicated by
inverting the subject and has/have. Negatives are made with not.
The simple present is just the base form of the verb. Questions are made with do and negative
forms are made with do not.In the third person singular, -s or -es is added. Questions are made
with does and negative forms are made with does not.
For all the grammatical tenses there are more specific categories that they call
"aspects". The aspect refers to the duration of an event within a grammatical
time. In other words, the aspect of an hour allows us to describe or understand
how it develops.
