Way over a covered walk (4)
I believe the answer is:
stoa
'covered walk' is the definition.
(I've seen this before)
'way over a' is the wordplay.
I cannot quite understand how this works, but
'way' could be 'st' (abbreviation for street) and 'st' is found within the answer.
'over' could be 'o' (cricket abbreviation) and 'o' is found in the answer.
'a' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for stoa that I've seen before include "Portico in ancient Greece" , "Where Zeno spoke" , "Ancient Greek portico" , "Philosophers' porch" , "classical colonnade" .)
