A few lie about old landlady (7)
I believe the answer is:
alewife
'old landlady' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'a few lie about' is the wordplay.
'about' indicates anagramming the letters.
'few'+'lie'='fewlie'
'fewlie' with letters rearranged gives 'lewife'.
'a'+'lewife'='ALEWIFE'
Can you help me to learn more?
(Other definitions for alewife that I've seen before include "superior, > swimmer found" , "serving fish" , "a catch" .)
