A Little
A Few, Few
adverb, noun
This word is a single kanji with hiragana attached, though there is no specific clue as to what type of word it is. That means you can usually guess it's a noun, adverb or na-adjective (in this case it's a noun / adverb). The meaning of this word is pretty much the same as the kanji, though, making it fairly easy. The kanji meaning for 少 is few, and the meaning of the vocab form is a little or a few.
