Rope in young woman, obliging initially (5)
I believe the answer is:
Here is my best explanation:
'rope in' is the definition.
(I've seen this before)
'young woman obliging initially' is the wordplay.
'young woman' becomes 'lass' (lass is a kind of young woman**).
'initially' indicates taking the first letters.
The first letter of 'obliging' is 'o'.
