Up to nothing in Paris, son's bored (6)
I believe the answer is:
arisen
'up' is the definition.
(I've seen this in another clue)
'nothing in paris son's bored' is the wordplay.
'nothing in paris' becomes 'aris' (I can't justify this - if you can you should give a lot more credence to this answer).
'son' becomes 'epigon' (I've seen this before).
'bored' suggests removing the centre (bore can mean to hollow out).
'epigon' with its middle removed is 'en'.
'aris'+'en'='ARISEN'
'to' is the link.
Can you help me to learn more?
(Other definitions for arisen that I've seen before include "Gone up" , "Sprung up" , "Up on the rocks" , "(Having) occurred" , "(Has) come into view; (has) originated (from)" .)
