Weed out of car and I teed head of AA off (9)
I believe the answer is:
eradicate
'weed out' is the definition.
(thesaurus)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for eradicate that I've seen before include "scratch" , "Stamp out, remove all traces of" , "Kill" , "Expunge" , "Get rid of, eliminate entirely" .)
