Publication to pass over material (8)
I believe the answer is:
organdie
'material' is the definition.
(organdie is a kind of material)
'publication to pass' is the wordplay.
'publication' becomes 'organ' (organ is a kind of publication).
'to pass' becomes 'die' (as in passing away).
'organ'+'die'='ORGANDIE'
'over' acts as a link.
(Other definitions for organdie that I've seen before include "I raged on about the fabric" , "Fine material" , "I groaned about translucent fabric" , "Cotton fabric used for dresses" , "Fine stiffened translucent fabric" .)
