Potential big name actor going around college: time to go red (7)
I believe the answer is:
scarlet
'red' is the definition.
(I know that scarlet is a type of red)
'potential big name actor going around college time to' is the wordplay.
I cannot quite understand how this works, but
'name' could be 'car' and 'car' is found in the answer.
'time' could be 't' (abbreviation) and 't' is found in the answer.
This explanation may well be incorrect...
'go' is the link.
Can you help me to learn more?
(Other definitions for scarlet that I've seen before include "Red colour of clarets" , "Brilliant red colour" , "Fallen" , "Clarets (anag.)" , "immoral" .)
