Arrive in company with me (4)
I believe the answer is:
come
'arrive in' is the definition.
(thesaurus)
'company with me' is the wordplay.
'company' becomes 'co' (abbreviation).
'with' says to put letters next to each other.
'co'+'me'='COME'
(Other definitions for come that I've seen before include "Draw near" , "Approach" , "Arrive" , "See 13 across" , "Turn up" .)
