Not designated as different salesmen (8)
I believe the answer is:
nameless
'not designated' is the definition.
The answer and definition are different parts of speech. However, past participle verbs and adjectives can sometimes mean the same thing.
'different salesmen' is the wordplay.
'different' indicates anagramming the letters (letters placed in a different order).
'salesmen' anagrammed gives 'NAMELESS'.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for nameless that I've seen before include "This undistinguished" , "Untitled" , "Lacking means of identification" , "Too horrific to be described" , "Salesmen lacking identity" .)
