Repelled by new precious metal in a chair (9)
I believe the answer is:
nauseated
'repelled' is the definition.
(nauseating is a kind of repelling)
'by new precious metal in a chair' is the wordplay.
'by' says to put letters next to each other.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'precious metal' becomes 'au' (chemical symbol of gold).
'in a chair' becomes 'seated' (I've seen this in another clue).
'n' put next to 'au' is 'nau'.
'nau'+'seated'='NAUSEATED'
(Other definitions for nauseated that I've seen before include "Sickened" , "Revolted" , "Disgusted" .)
