Make eyes at the Spanish turn making a comeback (4)
I believe the answer is:
ogle
'make eyes at' is the definition.
(thesaurus)
'the spanish turn making a comeback' is the wordplay.
'the spanish' becomes 'el'.
'turn' becomes 'go' (a person's move in a board game).
'making a comeback' shows that the letters should be reversed in order.
'el'+'go'='elgo'
'elgo' in reverse letter order is 'OGLE'.
(Other definitions for ogle that I've seen before include "Eye lecherously" , "as lecher might do?" , "flirtatious look" , "Leer" , "Look at lecherously" .)
