Material worn by sedentary workers? (5)
I believe the answer is:
satin
'material' is the definition.
(I know that satin is a type of material)
'worn by sedentary workers?' is the wordplay.
I cannot quite understand how this works, but
'by' could be 'at' and 'at' is located in the answer.
The remaining letters 'sin' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for satin that I've seen before include "Smooth glossy fabric" , "Shiny solk" , "Saint (anag.)" , "Material with glossy front and dull back" , "Silky material" .)
