When Did Oblige Become a Word?

The word oblige has been used since the year 1300 as the Middle English obligen, meaning to bind by oath or put under moral or legal obligation.

What is the origin of the word oblige?

Oblige derives via Middle English and the Anglo-French obliger from Latin obligare ("to bind to"), a combination of ob- ("to or toward") and ligare ("to bind"), whereas obligate descends directly from obligatus, the Latin past participle of obligare.

Is obligated a real word?

Obligated is both the simple past tense and past participle form of obligate. It becomes a rough synonym of required, like in the phrase obligated responsibilities. Usually, though, it would be more common to use the noun obligations instead.
