Get rid of a timeline error (9)
I believe the answer is:
eliminate
'get rid' is the definition.
(I've seen this before)
'a timeline error' is the wordplay.
'error' indicates an anagram.
'a'+'timeline'='atimeline'
'atimeline' with letters rearranged gives 'ELIMINATE'.
'of' acts as a link.
(Other definitions for eliminate that I've seen before include "Exclude from further stage of competition" , "waste" , "Discard - exclude" , "defeat" , "put out" .)
