Produce (an egg) (3)
I believe the answer is:
lay
'produce an egg' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lay that I've seen before include "Not ordained; song" , "Not ordained into clergy" , "Deposit < , as a nest egg, was" , "Not clerical or professionally qualified" , "bed" .)
