To many, a comic cat (3)
I believe the answer is:
tom
'a comic cat' is the definition.
'tom' can be an answer for 'cat' (a tom is a male cat). I'm not certain of the 'a comic' bit.
'to many' is the wordplay.
'many' becomes 'm' (Roman numeral for a thousand).
'to'+'m'='TOM'
Can you help me to learn more?
(Other definitions for tom that I've seen before include "A male domestic cat" , "He is associated with Dick and Harry" , "famous schoolboy" , "Thumb" , "Waits, perhaps" .)
