Relish being similar (4)
I believe the answer is:
like
This clue is a double definition.
'relish' is the first definition.
(I've seen this before)
'similar' is the second definition.
(synonyms)
'being' acts as a link.
(Other definitions for like that I've seen before include "a match?" , "One of the same kind" , "Enjoy; similar" , "Approve; be fond of" , "Care for - much the same" .)
