Republican expert with husky, say - a fast animal (9)
I believe the answer is:
racehorse
'a fast animal' is the definition.
'racehorse' can be an answer for 'animal' (I've seen this before). I am not sure about the 'a fast' bit.
'republican expert with husky say' is the wordplay.
'republican expert' becomes 'race' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'with' is a charade indicator (letters next to each other).
'husky' becomes 'hoarse' (synonyms).
'say' indicates a 'sounds like' (homophone) clue.
'hoarse' is a homophone of 'horse'.
'race'+'horse'='RACEHORSE'
Can you help me to learn more?
(Other definitions for racehorse that I've seen before include "Arab possibly" , "runner" , "Animal" , "Steeplechaser, maybe" , "Which a jockey rides" .)
