Road surface makes menu bit odd (7)
I believe the answer is:
bitumen
'road surface' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'menu bit odd' is the wordplay.
'odd' indicates anagramming the letters.
'menu'+'bit'='menubit'
'menubit' with letters rearranged gives 'BITUMEN'.
'makes' is the link.
Can you help me to learn more?
(Other definitions for bitumen that I've seen before include "Road-surfacing material" , "Substance for surfacing roads" , "Mixed-up tar" , "might be used to 16 [RESURFACE]" , "Material for road surfacing, roofing, etc" .)
