Obscure description of book that's unfinished (4)

Ross

I believe the answer is:

blur

'obscure' is the definition.
(both can mean to vague or indistinct)

'description of book that's unfinished' is the wordplay.
'description of book' becomes 'blurb' (description on the back of a book).
'that's unfinished' means to remove the last letter.
'blurb' with its last letter taken off is 'BLUR'.

(Other definitions for blur that I've seen before include "Unfocused image" , "Smudge - Britpop band" , "Out-of-focus image" , "Haze - obscure" , "Out-of-focus sight" .)

I've seen this clue in The Times.
