Extended November in one's youth in area of NY (4,6)
I believe the answer is:
long island
'area of ny' is the definition.
The answer and definition can be both locations as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'extended november in one's youth' is the wordplay.
'extended' becomes 'long' (extended can mean longer than usual).
'november' becomes 'N' (phonetic alphabet: alpha, bravo, charlie etc.).
'in' means one lot of letters goes inside another.
'one's' becomes 'i's' (Roman numeral).
'youth' becomes 'lad' (lad means a young man).
'is'+'lad'='islad'
'n' put into 'islad' is 'island'.
'long'+'island'='LONG ISLAND'
'in' is the link.
Can you help me to learn more?
(Other definitions for long island that I've seen before include "part of America" , "patch cut off in New York" , "Part of New York" .)
