Saw things in Société Ethnologique? (5)
I believe the answer is:
teeth
'saw things' is the definition.
(parts of a saw)
'in societe ethnologique?' is the wordplay.
'in' says the answer is hidden in the clue.
'TEETH' is hidden in the letters of 'societe ethnologique'.
(Other definitions for teeth that I've seen before include "Canines, molars, etc" , "Genuine effectiveness" , "Dentures" , "Bony structures for eating" , "Being in your face" .)
