Sarah’s Word of the Day for 17 March 2010 is “indubitably.” The first time I recall encountering this word was  when I was in high school (so between the years of 1994 and 1999), when the character of Beast used it in Uncanny X-Men.


/ɪnˈdubɪtəbəl, -ˈdyu-/ [in-doo-bi-tuh-buhl, -dyoo-]


that cannot be doubted; patently evident or certain; unquestionable.
