Novice, trainee (7)
I believe the answer is:
learner
I believe this clue is a double definition.
'novice' is the first definition.
(I know that learner is a type of novice)
'trainee' is the second definition.
(I've seen this before)
(Other definitions for learner that I've seen before include "One under tuition" , "Amateur" , "Driver under instruction" , "Tyro" , "Pupil or apprentice" .)
