Complimentary expression for all-in wrestling? (9)
I believe the answer is:
freestyle
'all-in wrestling?' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'complimentary expression' is the wordplay.
'complimentary' becomes 'free' (synonyms).
'expression' becomes 'style'.
'free'+'style'='FREESTYLE'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for freestyle that I've seen before include "Race where swimmers can choose what stroke to use" , "with little regulation" , "Crawl, usually" , "Race with few restrictions on technique" , "How one may swim" .)
