Send out some remittances (4)
I believe the answer is:
emit
'send out' is the definition.
(I've seen this before)
'some remittances' 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 'remittances'.
(Other definitions for emit that I've seen before include "Give out (eg light)" , "Come out!" , "Give off or discharge" , "Issue" , "Send forth" .)
