Camera operator terrible prig (4)
I believe the answer is:
grip
'camera operator' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'terrible prig' is the wordplay.
'terrible' is an anagram indicator.
'prig' with letters rearranged gives 'GRIP'.
Can you help me to learn more?
(Other definitions for grip that I've seen before include "Hold tightly in hand" , "Grab" , "item of baggage" , "one on film set" , "Hold hard" .)
