I had since worked out that the fourth letter is P so, with your help, PLAIN +CHA got me there. (I was completely on the wrong track to begin with.)
Thanks once again malone.
Can you assist with this one:
9a Publication to pass on material (8)
9 A. A five-letter word for 'publication', often used in crosswords, and add the usual three-letter word for 'to pass on'. The answer is a material, fabric.
