Annoyed by gesture of respect, one may get fired (8)
I believe the answer is:
crossbow
'respect one may get fired' is the definition.
I can't judge whether this definition defines the answer.
'annoyed by gesture' is the wordplay.
'annoyed' becomes 'cross' (cross can mean angry).
'by' is a charade indicator (letters next to each other).
'gesture' becomes 'bow' (bowing is a kind of gesturing).
'cross'+'bow'='CROSSBOW'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for crossbow that I've seen before include "Ancient weapon, shot bolts" , "One responsible for shooting bolts" , "William Tell's weapon" , "Weapon for shooting bolts" , "Weapon (used to set off a quarrel?)" .)
