Car you can get in ultramarine (4)
I believe the answer is:
tram
'car' is the definition.
(as in a tram car)
'can get in ultramarine' is the wordplay.
'TRAM' is hidden within the letters.
But, I'm unsure how this is indicated.
'you' is the link.
Can you help me to learn more?
(Other definitions for tram that I've seen before include "Former public vehicle" , "Streetcar" , "Old city transport, ram on rails through streets" , "Street vehicle running on rails" , "An early form of Luas in Dublin transport" .)
