adj. providing an advantage; favorable or beneficial
adj. conducive to success or improvement
The word "advantageous" derives from the noun "advantage," which entered Middle English from Old French avantage (meaning "superior position, profit"), itself stemming from avant ("before") + -age (noun-forming suffix). The suffix -ous (from Latin -osus) was added to form the adjective, implying "full of advantage." The logical progression reflects the idea of a state or quality that confers benefit or superiority.
