Make eyes at the Spanish turn making a comeback (4)
I believe the answer is:
Here is my best explanation:
'make eyes at' is the definition.
(I've seen this before)
'the spanish turn making a comeback' is the subsidiary indication.
'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.
'elgo' written backwards gives 'ogle'.
(Other definitions for ogle that I've seen before include "give the glad eye", "Leer", "Amorous glance", "Look with desire", "Perv", "Eye greedily", "Cast flirtatious glance at", "Eye lecherously", "Gape at" and "View lecherously".)
