Almost accomplished, lines varied (7)
I believe the answer is:
diverse
'varied' is the definition.
(I've seen this before)
'almost accomplished lines' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'accomplished' becomes 'did' (doing is a kind of accomplishing).
'lines' becomes 'verse' (I've seen this before).
'did' with its final letter removed is 'di'.
'di'+'verse'='DIVERSE'
(Other definitions for diverse that I've seen before include "Multifarious" , "Of different kind or variety" , "Revised, being of different kinds" , "Many and varied" , "'Various, assorted (7)'" .)
