Top student for a good source of income? (6)
I believe the answer is:
earner
'a good source of income?' is the definition.
I can't judge whether this definition defines the answer.
'top student' is the wordplay.
'top' means to remove the first letter.
'student' becomes 'learner' (I've seen this before).
'learner' with its first letter removed is 'EARNER'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for earner that I've seen before include "Someone, or something, that provides income" , "dubious money-making scheme" , "Means of acquiring money" , "One bringing in wage" , "lucrative job" .)
