Continuous Tenses

The continuous tenses include:

Present Continuous

Present Perfect Continuous

Past Perfect Continuous

Future Continuous

All these tenses are formed with the progressive (continuous) aspect.

This aspect indicates that an action or state, past, present, or future, was, is or will be unfinished at the time referred to.

The continuous aspect is formed by the auxiliary verb "to be" and the -ing form (the present participle).
