Cross dishy bride's holding (6)
I believe the answer is:
hybrid
'cross' is the definition.
(thesaurus)
'dishy bride's holding' is the wordplay.
'holding' indicates the answer is hidden within the clue.
'HYBRID' can be found hidden inside 'dishy brides'.
(Other definitions for hybrid that I've seen before include "Plant grown from two different species" , "Mix of species" , "Cross breed" , "Offspring of two different species or varieties" , "Mongrel - cross" .)
