Aloft; rotten (4)
I believe the answer is:
high
I believe this is a double definition.
'aloft' is the first definition.
(thesaurus)
'rotten' is the second definition.
(thesaurus)
(Other definitions for high that I've seen before include "State of euphoria" , "having senior ranking?" , "Important, elevated" , "Way up" , "on a trip" .)
