Arrive to join me and the commander (4)
I believe the answer is:
come
'arrive' is the definition.
(synonyms)
'me and the commander' is the wordplay.
'and' is a charade indicator (letters next to each other) (I've seen this in other clues).
'the commander' becomes 'co'.
'me' put after 'co' is 'COME'.
'to join' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for come that I've seen before include "' - - fly with me'" , "Rude aggressive youth" , "Approach" , "Arrive" , "Turn up" .)
