Looked, started to go back then went ahead (5)
I believe the answer is:
ogled
'looked' is the definition.
(ogling is a kind of looking)
'go back then went ahead' is the wordplay.
'back' says the letters should be written in reverse.
'then' is a charade indicator (letters next to each other).
'went ahead' becomes 'led' (led the way).
'go' reversed gives 'og'.
'og'+'led'='OGLED'
'started to' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for ogled that I've seen before include "regarded with desire" , "Looked at lecherously" , "Stared at" , "Eyed in a lascivious manner" , "Looked flirtatiously at" .)
