Not all new ornaments are put on one's person (4)
I believe the answer is:
worn
'are put on one's person' is the definition.
The answer and definition can be both to do with fundamental existence as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
'not all new ornaments' is the wordplay.
'not all' indicates the answer is hidden within the clue (only some of the letters).
'WORN' is hidden in the letters of 'new ornaments'.
Can you help me to learn more?
(Other definitions for worn that I've seen before include "Frayed" , "Hackneyed, trite" , "Showing the effects of use" , "Sported on the body" , "Looking tired and exhausted" .)
