Ted's era? (9)
I believe the answer is:
edwardian
'ted's era?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'ted's era?' is the wordplay.
'ted' becomes 'edward' (I've seen this before).
'era?' becomes 'ian' (I can't justify this - if you can you should believe this answer much more).
'edward'+'ian'='EDWARDIAN'
Can you help me to learn more?
(Other definitions for edwardian that I've seen before include "from early twentieth century" , "The age before WW1" , "Early 20th-century" , "After Victoria" , "Of the fashion mocked by Teddy boys" .)
