Fixer in Sinai lauded (4)
I believe the answer is:
nail
'fixer' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see an association between them that I don't see?
'in sinai lauded' is the wordplay.
'in' indicates a hidden word.
'NAIL' is hidden in the letters of 'sinai lauded'.
Can you help me to learn more?
(Other definitions for nail that I've seen before include "'For want of a . . . . the shoe was lost'" , "Carpentry fastener" , "Fixing device" , "Apprehend" , "Brad or tack" .)
