Participator in your descent or ascent, oddly (8)
I believe the answer is:
ancestor
'participator in your descent' is the definition.
I can't judge whether this definition defines the answer.
'or ascent oddly' is the wordplay.
'oddly' indicates anagramming the letters.
'or'+'ascent'='orascent'
'orascent' anagrammed gives 'ANCESTOR'.
Can you help me to learn more?
(Other definitions for ancestor that I've seen before include "Forefather" , "Predecessor" , "Person from whom one is descended" , "one is up a tree" , "An escort (anag.)" .)
