Naked and possibly nuder two seconds before young Edward (9)
I believe the answer is:
undressed
'naked' is the definition.
(I've seen this before)
'possibly nuder two seconds before young edward' is the wordplay.
'possibly' indicates anagramming the letters.
'two seconds' becomes 'ss' (abbreviation for second times two).
'before' means one lot of letters go next to another.
'young edward' becomes 'ed' (short for Edward. I am not sure about the 'young' bit.).
'nuder' anagrammed gives 'undre'.
'undre'+'ss'+'ed'='UNDRESSED'
'and' is the link.
Can you help me to learn more?
(Other definitions for undressed that I've seen before include "Starkers" , "Took the clothes off" , "as a plain salad?" , "Stripped" , "Removed one's clothes" .)
