What does obligate mean?
Obligate means to bind a person or institution to an action, usually through a law, contract, formal duty, or strong moral responsibility. The phrase “obligate someone to do something” is especially common in legal and governmental writing: a regulation may obligate employers to disclose information, while a treaty may obligate states to meet certain standards. The word can also imply that a particular response is necessary, as in circumstances that obligate someone to withdraw. In contemporary English, “obligate” is more often encountered as a verb than as an adjective; when used adjectivally, “obligated” is usually clearer and more natural. The distinction from “oblige” is slight in many contexts, but “oblige” can additionally suggest a favour voluntarily performed, whereas “obligate” more strongly suggests a binding requirement. The word therefore appears frequently in contracts, statutes, regulations, institutional policies, and formal declarations of duty.
To bind or compel someone by law, contract, duty, or moral responsibility; to make an action necessary.

Where does obligate come from?
The word comes from Latin obligare, formed from ob- and ligare, both elements of which contribute the sense of binding or fastening. Latin obligatio developed into English obligation, and related English forms include oblige, obligatory, and obliging. The verb “obligate” entered English during the early 16th century, initially in legal contexts, and has retained its strongly formal and binding character.
