Keep a car on the road? (5)
I believe the answer is:
steer
'keep' is the definition.
The definition and answer can be both to do with social activities as well as being verbs in their base form.
Maybe you can see an association between them that I can't see?
'a car on the road?' is the wordplay.
'a car' becomes 'eer' (I can't justify this - if you can you should believe this answer much more).
'on' says to put letters next to each other.
'the road?' becomes 'st'.
'eer' put after 'st' is 'STEER'.
Can you help me to learn more?
(Other definitions for steer that I've seen before include "Guide, control" , "Exercise control" , "Direct; bullock" , "Direct movement" , "Direct; young ox" .)
