Eye apple, one to be given to teacher? (5)
I believe the answer is:
pupil
'eye' is the definition.
(thesaurus)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for pupil that I've seen before include "One in the eye or in place of learning" , "A student at school or eye part" , "part of my anatomy" , "I learn" , "Learner in the eye?" .)
