Harry meets Oprah, showing feeling (10)
I believe the answer is:
atmosphere
'feeling' is the definition.
(atmosphere can mean a feeling or mood)
'harry meets oprah' is the wordplay.
'harry' indicates anagramming the letters (harry can mean to attack or spoil).
'meets'+'oprah'='meetsoprah'
'meetsoprah' anagrammed gives 'ATMOSPHERE'.
'showing' is the link.
(Other definitions for atmosphere that I've seen before include "Feeling" , "blue?" , "We are always enveloped in this" , "prevailing mood" , "Spirit" .)
