I believe the answer is:
antique
'past' is the definition.
(thesaurus)
'clairvoyant i questioned about' is the wordplay.
'about' indicates the answer is hidden within the clue (the clue goes around or about the answer).
'ANTIQUE' can be found hidden inside 'clairvoyant i questioned'.
(Other definitions for antique that I've seen before include "Old relic" , "Venerably old" , "Object valued because of age" , "Item from an earlier time" , "Old collectable object" .)
