The way mousy types eat? (6)
I believe the answer is:
nibble
'eat?' is the definition.
(nibbling is a kind of eating)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for nibble that I've seen before include "express tentative interest" , "Take small bites of" , "Eat with small dainty bites, like mouse" , "Take tiny bites" , "Bite gently and eat a little at a time" .)
