Inventing tale, guard rang us for sweet substance (10,5)
I believe the answer is:
granulated sugar
'sweet substance' is the definition.
The definition suggests a singular noun which matches the answer.
'inventing tale guard rang us' is the wordplay.
'inventing' is an anagram indicator (I've seen 'invented' mean this).
'tale'+'guard'+'rang'+'us'='taleguardrangus'
'taleguardrangus' anagrammed gives 'GRANULATED SUGAR'.
'for' is the link.
Can you help me to learn more?
(Other definitions for granulated sugar that I've seen before include "sweetener needed" , "White sweetener" .)
