Two men from a bygone era (9)
I believe the answer is:
edwardian
'a bygone era' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'two men' is the wordplay.
'two men' means two substitutions for 'man'.
'man' becomes 'edward' (I've seen this before).
'man' becomes 'ian' (man's name).
'edward'+'ian'='EDWARDIAN'
'from' is the link.
Can you help me to learn more?
(Other definitions for edwardian that I've seen before include "From the years 1901 to 1910?" , "Early 20th-century" , "from early twentieth century" , "The age before WW1" , "Of the fashion mocked by Teddy boys" .)
