Give out terms of reference with no introduction (4)
I believe the answer is:
emit
'give out' is the definition.
(synonyms)
'terms of reference with no introduction' is the wordplay.
'terms of reference' becomes 'remit' (both can mean defined powers or responsibilities).
'with no introduction' means to remove the first letter.
'remit' with its initial letter taken off is 'EMIT'.
(Other definitions for emit that I've seen before include "Discharge - utter" , "Expel" , "Throw out" , "'Give off, odour say (4)'" , "Send out in time" .)
