Left a woman on the corner - flat! (5)

I believe the answer is:

level

I'm a little stuck... Click here to teach me more about this clue!

'flat' is the definition.
(I know that flat can be written as level)

'left a woman on the corner' is the wordplay.
'left' becomes 'l' (common abbreviation).
'a woman on the corner' becomes 'evel' (I can't explain this - if you can you should give a lot more credence to this answer).
'l'+'evel'='LEVEL'

Can you help me to learn more?

(Other definitions for level that I've seen before include "Uniform" , "Absolutely horizontal" , "Neither winning, nor losing" , "Regular" , "Floor; surveying device" .)

I've seen this clue in the Evening Standard.
