Give the little devil a name! (6)
I believe the answer is:
impart
'give' is the definition.
(I know that give can be written as impart)
'little devil a name' is the wordplay.
'little devil' becomes 'imp' (an imp is a little demon).
'a name' becomes 'art' ().
'imp'+'art'='IMPART'
'the' acts as a link.
(Other definitions for impart that I've seen before include "Divulge, pass on" , "Contribute" , "Give - tell" , "Give, say information, make known" , "Communicate (info)" .)
