Produce eastern maiden with sex appeal (4)
I believe the answer is:
emit
'produce' is the definition.
'eastern maiden with sex appeal' is the wordplay.
'eastern' becomes 'e'.
'maiden' becomes 'm' (cricket abbreviation).
'with' means one lot of letters go next to another.
'sex appeal' becomes 'it'.
'e'+'m'+'it'='EMIT'
(Other definitions for emit that I've seen before include "Give off, heat say" , "Conductor; telegram (US)" , "Release" , "Produce and discharge" , "Throw out" .)
