Have everybody behind you (7)
I believe the answer is:
precede
'have' is the definition.
The definition and answer can be both to do with social activities as well as being verbs in their base form.
Perhaps there's a link between them I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for precede that I've seen before include "Come before (something)" , "Go before (someone)" , "Walk in front of" , "Go in front" , "go before the others" .)
