Used to express that something is ‘slightly (A)’, ‘somewhat (A)’, or ‘in some respects (A)’ in Japanese is the phrase なくはない. This is comprised of ない in its なく (conjunctive) form connected to either verbs or nouns, は, and ない. The literal meaning of this structure is close to ‘it’s not that it isn’t (A)’, and is a type of double negative.
Although preceded mostly by verbs, this structure sometimes appears following nouns. When that is the case, が, は, or sometimes even に may be between なくはない and the noun. Additionally, the は in なくない is interchangeable with も, with only a slight strengthening of the nuance when も is used.

This structure often appears with the potential form of verbs, in order to show that something is not impossible, despite appearances or what one may think.
