An archaic spelling of 'advantage'; superiority or benefit in a position or circumstance.
From Old French 'avantage,' formed from 'avant' (before) + '-age' (condition). The variant 'avantage' was common in Middle English and early Modern English before standardization.
The spelling 'avantage' shows how English was fluid and flexible in medieval times—scribes hadn't yet standardized spelling, so the same word could be written multiple ways depending on who was writing!
