12 verb tenses of ‘begin‘.

When to use began or begun?

simple pastThe concert began with a fanfare from the brass section.
present perfectThe project has already begun, so we need to start working on it now.
began vs. begun

The first sentence uses began, which is the simple past conjugation. We communicate in the simple past to refer to actions or events that took place entirely in the past.

The past participle form is begun. It’s clear when a participle vs. a simple tense is in use because participles come with auxiliary verbs to create perfect or continuous tenses in grammar; such as the past perfect, past continuous, and present perfect/continuous aspects in grammar.

To form the past perfect tense, use the past participle (e.g., begun) with the auxiliary had. To form the present perfect tense, pair the past participle with have/has (has in the third-person present singular). These aspects of time describe describe events as continuous, or as ongoing for a certain period/slice of time up until another point.
