What does matsu mean in Japanese?

Answer 1

With that romaji it can mean several things like 蜜 /mi tsu/ [honey] and 密 /mi tsu/ [density]. You might mean 三つ for which the correct romaji would be 'mittsu', double 't' because of slight gemination on it. That would mean 'three' as a number, like 'mittsu onegai shimasu' [fig: please give me three of those].

Answer 2

As a noun, 'matsu' means 'pine tree' (松) in Japanese. The word 'matsu' may also be used to mean 'to wait' (待つ).

Answer 3

松葉 (matsuba) means "pine needles" in Japanese.
