The material about me is a gross fabrication (8)
I believe the answer is:
gossamer
'the material' is the definition.
(gossamer is a kind of material)
'me is a gross fabrication' is the wordplay.
I cannot quite understand how this works, but
'me' is present in the answer.
'a' is within the answer.
an anagram of 'gross' is 'gossr' which is within the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'about' acts as a link.
Can you help me to learn more?
(Other definitions for gossamer that I've seen before include "Filaments of a spider's web" , "Very finest textured silk" , "Fine spider-threads" , "Flimsy, delicate material" , "Some rags (anag.)" .)
