Present Tense and Present Continuous

Principal Parts and are both used to express something
that happens at the present time. The explanations below point
out when each is used.

The simple present tense form of any verb is identical to
Principal Part , the base form of the verb, except that -s
or -es is added to the base form of third-person singular forms.

Action in the present can be expressed in two ways — as the
simple present with one verb (see below, left side) and as the
present continuous with two verbs (see below, right side).

The present continuous states an action or condition

that is taking place at the present moment.
