How about drink before setting? (9)
I believe the answer is:
supposing
'how about drink before setting?' is the definition.
I can't judge whether this defines the answer.
'about drink before setting?' is the wordplay.
'about drink' becomes 'sup' (to sup is to drink. I am not sure about the 'about' bit.).
'before' says to put letters next to each other.
'setting?' becomes 'posing' (posing is a kind of setting).
'sup'+'posing'='SUPPOSING'
Can you help me to learn more?
(Other definitions for supposing that I've seen before include "Conjecturing, imagining" , "Fancying" , "Assuming to be true, suspecting" , "Hypothesising" .)
