Solitary person’s high honour featured in article abroad (8)
I believe the answer is:
lonesome
'solitary' is the definition.
(I know that solitary can be written as lonesome)
'person's high honour featured in article abroad' is the wordplay.
'person's' becomes 'one's' (belonging to an unspecified person).
'high honour' becomes 'OM' (Order of Merit).
'featured in' is an insertion indicator.
'article abroad' becomes 'le' (I am not sure about this - if you are sure you should believe this answer much more).
'ones'+'om'='onesom'
'onesom' put inside 'le' is 'LONESOME'.
Can you help me to learn more?
(Other definitions for lonesome that I've seen before include "Sad and lonely" , "Are you -- tonight (Elvis)" , "Sole" , "Abandoned" , "Loosen me, being solitary" .)
