Annoyed about what's left in deserted gallery (6)
I believe the answer is:
grumpy
'annoyed' is the definition.
Both the answer and definition are adjectives. Perhaps they are linked in a way I don't understand?
'what's left in deserted gallery' is the wordplay.
'what's left' becomes 'rump' (rump can mean the remainder).
'in' indicates putting letters inside.
'deserted' means to remove the middle letters (middle letters must vacate or desert the word).
'gallery' with its middle removed is 'gy'.
'rump' put into 'gy' is 'GRUMPY'.
'about' acts as a link.
Can you help me to learn more?
(Other definitions for grumpy that I've seen before include "Churlish" , "An ill-tempered dwarf of group of Seven" , "Peevish" , "Ill-tempered and crabby" , "Ill-humoured" .)
