He is entertained in the synagogue still (5)
I believe the answer is:
guest
'he' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'entertained in the synagogue still' is the wordplay.
'entertained in' indicates a hidden word.
'GUEST' is hidden in the letters of 'synagogue still'.
'is' is the link.
Can you help me to learn more?
(Other definitions for guest that I've seen before include "company" , "Someone invited" , "Person receiving another's hospitality" , "See 2" , "Visitor, lodger" .)
