Storey that's reached from above or below? (5)
I believe the answer is:
level
'storey' is the definition.
(synonyms)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for level that I've seen before include "Neither winning, nor losing" , "Having a flat, horizontal surface" , "Flush" , "Even - equal" , "Palindromic storey" .)
