Motorist waiting for chance to pass? (7)
I believe the answer is:
learner
'motorist' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for learner that I've seen before include "Student (of driving?)" , "Tyro" , "One ascertaining" , "Someone undergoing education" , "A student or beginner" .)
