River board offering description of water? (7)
I believe the answer is:
potable
'description of water?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'river board' is the wordplay.
'river' becomes 'po' (Italian river).
'board' becomes 'table' (both can mean food).
'po'+'table'='POTABLE'
'offering' acts as a link.
Can you help me to learn more?
(Other definitions for potable that I've seen before include "Able to be drunk" , "Fit for drinking" , "fit to ingest" , "having healthy water quality" , "Fit to drink" .)
