Glamorous former wife with old jerk (6)
I believe the answer is:
exotic
'glamorous' is the definition.
(thesaurus)
'former wife with old jerk' is the wordplay.
'former wife' becomes 'ex'.
'with' is a charade indicator (letters next to each other).
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'jerk' becomes 'tic' (I've seen this before).
'ex'+'o'+'tic'='EXOTIC'
(Other definitions for exotic that I've seen before include "Strange, rare or foreign" , "Romantically strange" , "Colourful and glamorous from abroad" , "Colourful or unusual, perhaps from abroad" , "Unusual and interesting" .)
