I cleverly coin a term for classical architecture (5)
I believe the answer is:
ionic
'architecture' is the definition.
(I've seen this before)
'i cleverly coin' is the wordplay.
'cleverly' indicates anagramming the letters (a clever or tricky version of the letters).
'coin' anagrammed gives 'onic'.
'i'+'onic'='IONIC'
'a term for classical' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for ionic that I've seen before include "entailing small charges" , "Pertaining to charged particle" , "Greek tongue" , "One of five classical orders of architecture" , "Classical style" .)
