Characterized by the tendency to wrongfully claim or assume something you don't deserve, especially authority or importance.
From arrogate (verb) + -ive (suffix indicating tendency or characteristic). The -ive suffix, from Latin -ivus, creates adjectives showing what something does or what quality it has.
An arrogative person has an automatic reflex to assume they're right and to claim credit—it's built into their personality pattern, not just a one-time mistake.
