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' means one lot of letters go next to another.
'somehow' indicates an anagram.
'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" .)
