Stirling letter from Moses (4)
I believe the answer is:
moss
'stirling' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see a link between them that I can't see?
'letter from moses' is the wordplay.
'letter' becomes 'e'.
'from' indicates named letters should be taken away.
'moses' with 'e' taken out is 'MOSS'.
Can you help me to learn more?
(Other definitions for moss that I've seen before include "Low-growing plant" , "Small plants growing as thick mat" , "Small flowerless green plant without proper roots" , "Plant(s) not wanted on lawns" , "Shape of pointed arch" .)
