Element of story that connects with readership (6)
I believe the answer is:
Here is my best explanation:
'story that connects with readership' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'element of' is the subsidiary indication.
'element' becomes 'th' (Th is an example).
'of' becomes 'read' (I can't justify this - if you can you should believe this answer much more).
(Other definitions for thread that I've seen before include "Line of cotton - plot (of book, film)", "Hatred (anag)", "Cotton strand", "What sewer takes", "Connecting line", "Ridge around a screw", "Train of thought - screw feature", "Fine cord of twisted fibers", "Cord - Internet chat room discussion" and "Length of spun cotton or wool".)
