Take the Spanish female supporters climbing (7)
I believe the answer is:
snaffle
'take' is the definition.
(I know that snaffle is a more specific form of the action take)
'the spanish female supporters climbing' is the wordplay.
'the spanish' becomes 'el' ('the' in Spanish).
'female' becomes 'f' (common abbreviation).
'supporters' becomes 'fans' (fan is a kind of supporter).
'climbing' says the letters should be written in reverse (in a down clue, letters climb up).
'el'+'f'+'fans'='elffans'
'elffans' back-to-front is 'SNAFFLE'.
(Other definitions for snaffle that I've seen before include "Get hold of" , "Kind of bit - take without permission" , "Capture" , "Illicitly take" , "Pinch" .)
