Skinned boar stuffed with five eggs (3)
I believe the answer is:
ova
'eggs' is the definition.
(I've seen this before)
'skinned boar stuffed with five' is the wordplay.
'skinned' means to look at the middle letters.
'stuffed with' means one lot of letters goes inside another (I've seen this in other clues).
'five' becomes 'v' ('V' can be a synonym of 'five').
The central letters of 'boar' are 'oa'.
'oa' going around 'v' is 'OVA'.
(Other definitions for ova that I've seen before include "Potential life sources" , "Prerequisite for procreation" , "Multiple Latin eggs" , "Female gametes" , "Fertility clinic stock!" .)
