Arrive with cycle at college (4,2)
I believe the answer is:
turn up
'arrive' is the definition.
(thesaurus)
'with cycle at college' is the wordplay.
'with' says to put letters next to each other.
'cycle' becomes 'turn' (I can't justify this - if you can you should believe this answer much more).
'at college' becomes 'up' ('up' can mean at university).
'turn' next to 'up' is 'TURN-UP'.
Can you help me to learn more?
(Other definitions for turn up that I've seen before include "surprise" , "make louder" , "Appear by chance - increase volume" , "Arrive (uninvited?)" , "Show" .)
