Things of no importance in glass? (5,4)
I believe the answer is:
small beer
This might be a double definition.
'things of no importance' is the first definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'glass?' is the second definition.
(I've seen this before)
'in' acts as a link.
Can you help me to learn more?
(Other definitions for small beer that I've seen before include "People or things of no importance" , "Half, perhaps" , "no significance" , "trivial stuff" , "Half, say" .)
