Some vague statements from a visitor (5)
I believe the answer is:
guest
'a visitor' is the definition.
(someone visiting a place)
'some vague statements from' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'GUEST' can be found hidden inside 'vague statements from'.
(Other definitions for guest that I've seen before include "Invited visitor" , "company" , "Someone invited" , "Visitant" , "Visitor, lodger" .)
