Frank account?

DIARY

A personal record where one might confess secrets or daily thoughts in writing.

This clue plays on the double meaning of "Frank." As an adjective, "frank" means honest or straightforward, so a "frank account" could describe a personal journal where someone writes openly. The answer "DIARY" fits because it’s also a homophone for "dear me," a phrase that might start a candid entry—like "Dear Diary." The pun ties the idea of honesty with the literal object.
