Singular beer ingredient (3)
I believe the answer is:
hop
This might be a double definition.
'singular' is the first definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'beer ingredient' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for hop that I've seen before include "Climbing plant - jump!" , "Cone which flavours beer" , "Informal dance" , "Move on one leg" , "1950s dance event" .)
