"While looking through the Perkins telescope [at Saturn] one night, a pugnacious [pʌɡˈneɪʃəs] 10-year-old commented, 'Hey! I only see one ring. Rip off!'" — Tom Burns, The Delaware (Ohio) Gazette, 23 Oct. 2024

pugnacious
adj [pʌɡˈneɪʃəs]

Someone described as pugnacious shows a readiness or desire to fight or argue.

Pugnacious comes from the Latin verb pugnare (meaning "to fight"), which in turn comes from the Latin word for "fist," pugnus.

Pugnare has also given us impugn ("to assail by words or arguments"), oppugn ("to fight against"), and repugnant.
