Hard to follow abridged article from beginning to end (7)
I believe the answer is:
through
'from beginning to end' is the definition.
(I've seen this before)
'hard to follow abridged article' is the wordplay.
'hard' becomes 'rough' (similar in meaning).
'to follow' means one lot of letters go next to another.
'abridged' means to remove the last letter.
'article' becomes 'the' (the 'definite article' part of speech).
'the' with its final letter taken off is 'th'.
'rough' put after 'th' is 'THROUGH'.
(Other definitions for through that I've seen before include "By means of - by way of" , "Per" , "clear" , "From beginning to end" , "made it to the next stage" .)
