Sharp emotion as glutton tours old French city (9)
I believe the answer is:
poignancy
'sharp emotion' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'glutton tours old french city' is the wordplay.
'glutton' becomes 'pig' (I've seen this before).
'tours' means one lot of letters goes inside another (to tour can mean to go around).
'old' becomes 'o' (abbreviation).
'french city' becomes 'Nancy' (city in France).
'pig' enclosing 'o' is 'poig'.
'poig'+'nancy'='POIGNANCY'
'as' acts as a link.
Can you help me to learn more?
(Other definitions for poignancy that I've seen before include "Sadness" , "Quality that can touch or move" , "such a rueful thing" , "sentiment" .)
