Conscript to check rounds, about a hundred (5)
I believe the answer is:
choco
'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'.
'ch'+'oco'='CHOCO'
'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".)
