Looked on girl's love, expecting doubt initially (5)
I believe the answer is:
ogled
'looked' is the definition.
(ogling is a kind of looking)
'girl's love expecting doubt initially' is the wordplay.
'girl' becomes 'og' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'initially' suggests taking the first letters.
The initial letters of 'love expecting doubt' is 'led'.
'og'+'led'='OGLED'
'on' acts as a link.
Can you help me to learn more?
(Other definitions for ogled that I've seen before include "Looked flirtatiously at" , "Looked at lecherously" , "Eyed in a lascivious manner" , "Longingly looked at" , "Stared at" .)
