Bring up only child to eat edges of scorching toast (5,4,5)
I believe the answer is:
raise ones glass
'child to eat edges of scorching toast' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'bring up only' is the wordplay.
I cannot quite understand how this works, but
'up' could be 'is' (I've seen this in other clues) and 'is' is found within the answer.
'only' could be 'one' (synonyms) and 'one' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for raise ones glass that I've seen before include "drink to celebrate" , "Drink a health (to)" , "Suggest drinking" .)
