Lining up trap: earlier be a victim of one? (7,2)

'up trap earlier be a victim of one?' is the definition.
I can't judge whether this defines the answer.

'lining' is the wordplay.
I cannot quite see how this works, but
an anagram of 'lining' is 'lingin' which is located in the answer.
The remaining letters 'fal' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
