Little devil with the skill to communicate (6)
I believe the answer is:
impart
'communicate' is the definition.
(impart can mean to communicate or pass on)
'little devil with the skill' is the wordplay.
'little devil' becomes 'imp' (an imp is a little demon).
'with' is a charade indicator (letters next to each other).
'the skill' becomes 'art' (both can mean a talent).
'imp'+'art'='IMPART'
'to' acts as a link.
(Other definitions for impart that I've seen before include "17 down (anag)" , "Convey information, make known" , "Make known, relate" , "Divulge about armpit" , "Transmit" .)
