Present Continuous
The present continuous tense is used to describe actions happening at the present moment, that will happen in the future, or that are ongoing in the present. The present continuous tense requires the auxiliary verb -be in the simple present tense (am / is / are) to be combined with the present participle of a dynamic verb. The present participle form of all verbs (regular and irregular) are formed by adding -ing to their infinitive form. This tense should only be used with dynamic verbs (actions that have a clear beginning and end) not stative verbs (actions that describe states).
Note: Some stative verbs have both a stative form and a dynamic form.
This tense is used:
1) To describe actions happening now.
2) To describe temporary situations.
3) To talk about a planned event that will happen in the future.
4) To describe actions that happen frequently.
5) To talk about things that are trending.
6) To talk about things that are changing, progressing, or developing.
Time Expressions
The present continuous tense is often used with frequency adverbs and frequency adverb phrases. However it is not necessary to always mention frequency with the present continuous tense and frequency time expressions are also used with every other verb tense In English. In some limited cases future time expressions can be used with the present continuous tense as well.
