Confined, but looked after the inner man in grand surroundings (5)
I believe the answer is:
'confined' is the definition.
(gating is a kind of confining)
'looked after the inner man in grand surroundings' is the wordplay.
I cannot quite understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found within the answer.
'man' could be 'ed' (short for Edward) and 'ed' is found in the answer.
'grand' could be 'g' (G is short for grand as in a thousand) and 'g' is located in the answer.
A single letter 'a' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
'but' acts as a link.
Can you help me to learn more?
(Other definitions for gated that I've seen before include "deprived of liberty for a while" , "Confined to college" , "Under curfew" , "Confined to school" , "Forbidden to leave college" .)
