Crossword Genius

Aptitude to be crooked? (4)

Ross

I believe the answer is:

bent

This clue is a double definition.

'aptitude' is the first definition.
(bent is a kind of aptitude)

'be crooked?' is the second definition.
(both can mean corrupt)

'to' acts as a link.

(Other definitions for bent that I've seen before include "Slang for dishonest or crooked" , "passion" , "Natural aptitude" , "Crooked - tendency" , "Twisted - corrupt" .)

I've seen this clue in The Times.
