Sophisticated, so it's said, after spells here, perhaps? (5,6)
I believe the answer is:
charm school
'sophisticated so it's said after spells here perhaps?' is the definition.
The definition suggests a singular noun which matches the answer.
'spells here perhaps?' is the wordplay.
I cannot really understand how this works, but
'spells' could be 'charms' (I've seen this before) and 'charms' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for charm school that I've seen is " female establishment".)
