Help as Brie deteriorates -- being this? (10)
I believe the answer is:
perishable
'this?' is the definition.
The definition and answer are not the same part of speech.
'help as brie deteriorates' is the wordplay.
'deteriorates' indicates anagramming the letters (I've seen 'deteriorating' mean this).
'help'+'as'+'brie'='helpasbrie'
'helpasbrie' is an anagram of 'PERISHABLE'.
'being' is the link.
Can you help me to learn more?
(Other definitions for perishable that I've seen before include "easily spoilt" , "won't last long" , "(Of food) likely to rot" , "Likely to rot quickly" , "Herbal pies (anag.)" .)
