Proper shock female being fired (5)
I believe the answer is:
right
'proper' is the definition.
(synonyms)
'shock female being fired' is the wordplay.
'shock' becomes 'fright' (I've seen this before).
'female' becomes 'f' (abbreviation).
'being fired' indicates named letters should be taken away (some letters are fired away).
'fright' with 'f' taken out is 'RIGHT'.
(Other definitions for right that I've seen before include "Correct; entitlement" , "Girth (anag)" , "A person is entitled to it" , "Correct - starboard" , "Authority - one hand" .)
