Conscript to check rounds, about a hundred (5)
I believe the answer is:
'conscript' is the definition.
Both the definition and answer are singular nouns.
Maybe there's an association between them I don't understand?
'check rounds about a hundred' is the wordplay.
'check' becomes 'ch' (abbreviation).
'rounds' becomes 'oo' (two O's - O is a round letter).
'about' is an insertion indicator.
'a hundred' becomes 'C' (Roman numeral).
'oo' placed around 'c' is 'oco'.
'to' is the link.
Can you help me to learn more?
(Another definition for choco that I've seen is " Pear-shaped vegetable like a cucumber".)
