Drive to support with a bit of help (6)
I believe the answer is:
propel
'drive' is the definition.
(I know that drive is a kind of propel)
'support with a bit of help' is the wordplay.
'support' becomes 'prop' (prop up can mean to support).
'with' says to put letters next to each other.
'a bit of help' becomes 'el' (I can't justify this - if you can you should give a lot more credence to this answer).
'prop'+'el'='PROPEL'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for propel that I've seen before include "Push forwards" , "Drive or push forward as with oars" , "Cause to move forward with force" , "Drive forwards" , "Give impetus to" .)
