Grumpy colleague finding it hard to make friends (7)
I believe the answer is:
bashful
'grumpy' is the definition.
Both the answer and definition are adjectives. Maybe they are linked in a way I don't understand?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for bashful that I've seen before include "Dwarf" , "reserved" , "Shovel and pick worker" , "Shy, timid" , "Snow White's self-consciously timid assistant" .)
