Drive to support the Spanish (6)
I believe the answer is:
propel
'drive' is the definition.
(I've seen this in another clue)
'support the spanish' is the wordplay.
'support' becomes 'prop' (prop up can mean to support).
'the spanish' becomes 'el' ('the' in Spanish).
'prop'+'el'='PROPEL'
'to' is the link.
(Other definitions for propel that I've seen before include "Cause to move forward with force" , "Drive forwards" , "Launch" , "Push forwards" , "Give impetus to" .)
