What verb tense should a memoir be in?

Answer 1

memoir is a noun so it shouldn't be in any verb tense.

But the noun memoir can be used in any verb tense.

present - He is writing his memoirs.

past - He finished writing his memoirs last year.

future - He is going to publish his memoirs next year.

Answer 2

A memoir is typically written in the past tense, as the events being recounted have already taken place. This helps create a sense of distance and reflection, allowing the author to tell their story while reflecting on the lessons learned or the impact of the experiences.
