Intriguing woman supported by old Spanish gentleman (9)
I believe the answer is:
caballero
'spanish gentleman' is the definition.
(I've seen this before)
'intriguing woman supported by old' is the wordplay.
'intriguing woman' becomes 'caballer' (I can't justify this - if you can you should give a lot more credence to this answer).
'supported by' is a charade indicator (letters next to each other) (in a down clue, some letters hold up others).
'old' becomes 'o' (abbreviation).
'caballer'+'o'='CABALLERO'
Can you help me to learn more?
(Other definitions for caballero that I've seen before include "Spanish gentleman" , "Horseman" , "Spanish gent" , "Bear local away for Spanish cavalier" , "Foreign gentleman" .)
