Some nice mittens to give out (4)
I believe the answer is:
emit
'give out' is the definition.
(I know that give out can be written as emit)
'some nice mittens to' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'EMIT' is hidden in the letters of 'nice mittens to'.
(Other definitions for emit that I've seen before include "Come out!" , "Throw out" , "Send forth" , "Send out in time" , "Release" .)
