何～
なん～ · nan～ · JLPT N5 · noun
what sort of ~
何 (nan) = what; glued to a word it asks what sort of or how many
何 is the kanji for what, read nani alone and clipped to nan before another word. As a prefix it turns the next word into a question: 何人 = how many people, 何色 = what colour. Sound hook: nan sounds like none, as in none known yet, so you ask.
