Knight wearing a trilby, working hard in maze (9)
I believe the answer is:
labyrinth
'maze' is the definition.
(I know that maze can be written as labyrinth)
'knight wearing a trilby working hard' is the wordplay.
I cannot really understand how this works, but
'knight' could be 'n' (chess abbreviation) and 'n' is found within the answer.
'a' is within the answer.
an anagram of 'trilby' is 'lbyrit' which is located in the remaining letters.
'hard' could be 'h' (abbreviation used in pencil classifications) and 'h' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'in' acts as a link.
Can you help me to learn more?
(Other definitions for labyrinth that I've seen before include "Passages in cutting" , "It makes access difficult" , "confusing process" , "Complex network of passages" , "listening equipment" .)
