The present continuous or present progressive is one of the present tenses used in English, the others are the present simple and present perfect. All of them can be used in both the indicative and the subjunctive mood.

Use differences

The difference is very clear, the present continuous indicates actions that happen while you speak, the present simple indicates habitual or permanent actions. For example:

Peter goes to the supermarket on Saturdays.
(Peter goes to the supermarket on Saturdays).

Peter is driving to his office now.
(Peter is driving into his office now).

When is present simple used and when is present continuous?

Generally we use the present simple to talk about habitual situations and the present continuous for actions that are being carried out at that moment, but there are times when this differentiation is not possible.

Formation of the "present continuous"

The "present continuous" of any verb is made up of two parts: the present of the verb to be + the "present participle" of the main verb.

To form the past simple

we use the infinitive and add the ending “-ed”. The form is the same for all people (I, you, he, she, it, we, they).

Examples:
 want → wanted
 learn → learned
 stay → stayed
 walk → walked
 show → showed
