A character to see and copy (5)
I believe the answer is:
mimic
'copy' is the definition.
(mimicking is a kind of copying)
'a character to see and' is the wordplay.
'a character' becomes 'c'.
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'see and' becomes 'mimi' (I am not sure about this - if you are sure you should believe this answer much more).
'c' put after 'mimi' is 'MIMIC'.
Can you help me to learn more?
(Other definitions for mimic that I've seen before include "Impressionist" , "Ape" , "Imitate in order to ridicule" , "Go round a bend (in car)" , "Skilled imitator" .)
