She lived to sort out tangle (8)
I believe the answer is:
dishevel
'tangle' is the definition.
(I know that tangle can be written as dishevel)
'she lived to sort' is the wordplay.
'to sort' indicates an anagram.
'she'+'lived'='shelived'
'shelived' is an anagram of 'DISHEVEL'.
'out' acts as a link.
(Other definitions for dishevel that I've seen before include "Disarrange - rumple" , "Make untidy" , "Get ruffled" , "get into a mess" , "Disorder, ruffle" .)
