Shed one saw the two novices hiding in (7)
I believe the answer is:
spilled
'shed' is the definition.
(synonyms)
'one saw the two novices hiding in' is the wordplay.
'one saw' becomes 'spied' (I've seen this in another clue).
'the two novices' becomes 'll' (an abbreviation for learner driver written twice. I am not sure about the 'two' bit.).
'hiding in' indicates putting letters inside.
'spied' placed around 'll' is 'SPILLED'.
Can you help me to learn more?
(Another definition for spilled that I've seen is " shed".)
