Broken ore reveals eggs (3)
I believe the answer is:
roe
'eggs' is the definition.
(fish eggs)
'broken ore' is the wordplay.
'broken' indicates an anagram.
'ore' is an anagram of 'ROE'.
'reveals' is the link.
(Other definitions for roe that I've seen before include "Part of fish, sounds like go through water" , "Caviar" , "Fish eggs; small deer" , "Lobster's ripe ovary" , "Swift runner" .)
