Issue English staff had (7)
I believe the answer is:
emanate
'issue' is the definition.
(both can mean to give out or radiate)
'english staff had' is the wordplay.
'english' becomes 'E' (abbreviation).
'staff' becomes 'man' (as in staffing or manning a particular place).
'had' becomes 'ate' ('have' can mean 'eat').
'e'+'man'+'ate'='EMANATE'
(Other definitions for emanate that I've seen before include "Come out (of source)" , "Send out" , "Flow or proceed from" , "spring" , "Issue or spread out from a source" .)
