Group gets caught in another (4)
I believe the answer is:
sect
'in another' is the definition.
I can't judge whether this definition defines the answer.
'group gets caught' is the wordplay.
'group' becomes 'set' (both can mean a collection).
'gets' is an insertion indicator (gets can mean captures or absorbs).
'caught' becomes 'c' (cricket abbreviation).
'set' placed around 'c' is 'SECT'.
Can you help me to learn more?
(Other definitions for sect that I've seen before include "Subdivision of a larger religious group" , "Body of followers" , "Nonconformist faction" , "Denomination" , "Cult group" .)
