The Spanish wait is over — it's safe to eat (6)
I believe the answer is:
edible
'safe to eat' is the definition.
(I've seen this before)
'the spanish wait is over' is the wordplay.
'the spanish' becomes 'el'.
'wait' becomes 'bide' (I've seen this before).
'is over' is a reversal indicator.
'el'+'bide'='elbide'
'elbide' back-to-front is 'EDIBLE'.
'it's' acts as a link.
(Other definitions for edible that I've seen before include "Digestible" , "Comestible" , "description of fare" , "Fit to eat" , "Able to be eaten" .)
