Guy is last (4)

I believe the answer is:

stay

I believe this is a double definition.

'guy' is the first definition.
(thesaurus)

'is last' is the second definition.
(thesaurus)

(Other definitions for stay that I've seen before include "Supporting rod" , "Remain - support" , "Sojourn" , "Reside" , "Stick around" .)

I've seen this clue in The Telegraph.
