Room to get taxi home (5)
I believe the answer is:
cabin
'room' is the definition.
(cabin is a kind of room)
'get taxi home' is the wordplay.
'get' says to put letters next to each other.
'taxi' becomes 'cab' (synonyms).
'home' becomes 'in' ('he's home' can mean 'he's in').
'cab' next to 'in' is 'CABIN'.
'to' acts as a link.
(Other definitions for cabin that I've seen before include "Building" , "Shipboard room" , "modest accommodation" , "Wooden shack" , "Wooden hut" .)
