See a silly imitator prance about (5)
I believe the answer is:
caper
'prance about' is the definition.
'caper' can be an answer for 'prance' (I've seen this in another clue). I'm not certain of the 'about' bit.
'see a silly imitator' is the wordplay.
'see' becomes 'C' (the word for the letter, according to Chambers).
'a silly imitator' becomes 'aper' (synonyms. I am not sure about the 'silly' bit.).
'c'+'aper'='CAPER'
Can you help me to learn more?
(Other definitions for caper that I've seen before include "bound" , "Frolic - bud used in cooking" , "Escapade with an edible bud?" , "The Italian Job, perhaps" , "Something in the sauce" .)
