Buddy has a row with a chivalrous type (7)
I believe the answer is:
paladin
'a chivalrous type' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'buddy has a row' is the wordplay.
'buddy' becomes 'pal' (both can mean a friend).
'has' is a charade indicator (letters next to each other).
'row' becomes 'din' (both can mean a loud disturbance).
'pal'+'a'+'din'='PALADIN'
'with' is the link.
Can you help me to learn more?
(Other definitions for paladin that I've seen before include "hero" , "Historical knight" , "Knightly champion" , "Heroic knight - aid plan (anag)" , "Knight errant; a peer of Charlemagne" .)
