Introduction to timely subject in paper? (6)
I believe the answer is:
tissue
'paper?' is the definition.
(tissue paper is a kind of paper)
'introduction to timely subject' is the wordplay.
'introduction to' suggests taking the first letters (I've seen 'introductions to' mean this).
'subject' becomes 'issue' (synonyms).
The first letter of 'timely' is 't'.
't'+'issue'='TISSUE'
'in' acts as a link.
(Other definitions for tissue that I've seen before include "collection of lies, perhaps" , "Disposable hankie" , "See 17" , "Jewish religious leader" , "Fine soft paper" .)
