Notes poet describing mature woman (6)
I believe the answer is:
granny
'mature woman' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'notes poet describing' is the wordplay.
'notes' becomes 'nn' (the abbreviation for note repeated).
'poet' becomes 'gray' (n8th-century poet Thomas Gray).
'describing' indicates putting letters inside (describe can mean to form the outline of).
'nn' going within 'gray' is 'GRANNY'.
Can you help me to learn more?
(Other definitions for granny that I've seen before include "Family relative" , "Female relative" , "one possibly given a flat?" , "Insecure knot" , "Elderly relative's attempt at tying string?" .)
