An archaic or obsolete term relating to bearing or demeanor; proper deportment or conduct.
Possibly from Old French 'baisance' or related to 'bias' (inclination or bearing). This word is extremely rare in historical texts and may represent a variant or misrecording of other conduct-related terms.
This word is so obscure that even comprehensive historical dictionaries aren't entirely sure of its origin—it's a linguistic ghost word that hints at how many words got lost when English standardized in the printing press era.
