Snack sprightly bachelor brought in for maiden (6)
I believe the answer is:
nibble
'snack' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for nibble that I've seen before include "Bite off very small pieces" , "Bite gently and eat a little at a time" , "Snack" , "Eat with small dainty bites, like mouse" , "Take small bites of" .)
