Equal in both directions? (5)
I believe the answer is:
level
'equal' is the definition.
(I've seen this in another clue)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for level that I've seen before include "On equal terms" , "Tier; calm and steady" , "Horizontal plane - a palindrome" , "Come clean" , "Balanced" .)
