Appropriate condition (4)
I believe the answer is:
nick
I believe this clue is a double definition.
'appropriate' is the first definition.
(both can be verbs meaning 'steal' or 'take')
'condition' is the second definition.
(as in the phrase 'in good nick')
(Other definitions for nick that I've seen before include "Small cut; steal" , "Appropriate" , "cooler" , "go off with > form" , "Old . . . . Is a name for the devil" .)
