Charlie, child of the 60s, a bit resentful? (6)
I believe the answer is:
chippy
'resentful?' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for chippy that I've seen before include "One of two eating oysters" , "Oversensitive - traditional British food shop" , "Irritable; carpenter" , "Carpenter - for fried food!" , "employee of building firm?" .)
