One smooth student enrolled for Easter? (6)
I believe the answer is:
island
'for easter?' is the definition.
(Easter Island is an example)
'one smooth student enrolled' is the wordplay.
I cannot quite understand how this works, but
'one' could be 'an' (an apple is one apple) and 'an' is present in the answer.
'student' could be 'l' (as in L-plates for learner drivers) and 'l' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for island that I've seen before include "Land mass enclosed by water" , "See 12" , "See 1" , "Land mass not bordering another" , "See 2" .)
