leather

'material' is the definition.
(I've seen this before)

'nonsense writer pens the' is the wordplay.
'nonsense writer' becomes 'lear' (I have seen 'comic writer' mean 'lear' so perhaps 'writer' could also mean 'lear'. I am not sure about the 'nonsense' bit.).
'pens' is an insertion indicator.
'lear' placed around 'the' is 'LEATHER'.

Can you help me to learn more?

(Other definitions for leather that I've seen before include "calf" , "Beat" , "A tanner produces it from hide" , "Cured animal hide" , "Animal skins" .)
