Working on a script involving Dev running off with a lover (10)
I believe the answer is:
developing
'working on a script involving dev' is the definition.
I can't tell whether this definition defines the answer.
'running off with a lover' is the wordplay.
'running off' becomes 'eloping' ('elope' can be a synonym of 'run off').
'with' says to put letters next to each other.
'a lover' becomes 'dev' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'eloping' put after 'dev' is 'DEVELOPING'.
Can you help me to learn more?
(Another definition for developing that I've seen is " Converting (open land) to buildings".)
