They have jobs in the theatre or in religious work (6)
I believe the answer is:
actors
'they have jobs in the theatre' is the definition.
The definition suggests an adverb but the answer is not.
'or in religious work' is the wordplay.
'in' indicates putting letters inside.
'religious work' becomes 'acts' (I've seen this before).
'or' placed within 'acts' is 'ACTORS'.
Can you help me to learn more?
(Other definitions for actors that I've seen before include "Cast" , "Thespians" , "They 23 down" , "Players on stage" , "The Gleeson boys, say" .)
