Learner in right school found in the playground (6)
I believe the answer is:
slides
'in the playground' is the definition.
I can't tell whether this definition defines the answer.
'learner in right school' is the wordplay.
'learner' becomes 'l' (as in a learner driver with L-plates on their car).
'in' means one lot of letters goes inside another.
'right school' becomes 'sides' (I can't justify this - if you can you should believe this answer much more).
'l' inserted within 'sides' is 'SLIDES'.
'found' acts as a link.
Can you help me to learn more?
(Other definitions for slides that I've seen before include "Pieces of glass under the microscope" , "Sloping chutes in the playground" , "Sloping chutes in playgrounds" , "Pieces of glass for study of specimens" , "Slips, slithers" .)
