Hobo in me can show genial manner (8)

I believe the answer is:

bonhomie

I'm a little stuck... Click here to teach me more about this clue!

'genial manner' is the definition.
The answer and definition can be both human attributes as well as being singular nouns.
Perhaps there's a link between them I don't understand?

'hobo in me can' is the wordplay.
'can' indicates anagramming the letters (I've seen 'canned' mean this (canned can mean drunk)).
'hobo'+'in'+'me'='hoboinme'
'hoboinme' anagrammed gives 'BONHOMIE'.

'show' acts as a link.

Can you help me to learn more?

(Other definitions for bonhomie that I've seen before include "Warmth" , "'Affability, geniality (8)'" , "Exuberant friendliness - goodwill" , "genial nature" , "convivial feeling" .)
