Drive to get support for the Spanish (6)
I believe the answer is:
propel
'drive' is the definition.
(I know that drive is a more specific form of the action propel)
'support for the spanish' is the wordplay.
'support' becomes 'prop' (prop up can mean to support).
'for' means one lot of letters go next to another.
'the spanish' becomes 'el' ('the' in Spanish).
'prop'+'el'='PROPEL'
'to get' acts as a link.
(Other definitions for propel that I've seen before include "Drive or push forward as with oars" , "Drive forwards" , "Push forwards" , "Cause to move forward with force" , "Give impetus to" .)
