Finish getting toes dry somehow (7)
I believe the answer is:
destroy
'finish' is the definition.
(thesaurus)
'getting toes dry somehow' is the wordplay.
'getting' says to put letters next to each other.
'somehow' is an anagram indicator.
'toes' put after 'dry' is 'drytoes'.
'drytoes' anagrammed gives 'DESTROY'.
(Other definitions for destroy that I've seen before include "Annihilate" , "'Demolish, ruin (7)'" , "Soundly defeat" , "Ruin, put an end to" , "Demolish; pull down" .)
