What does mission mean?
A mission is a clearly defined task, assignment, or purpose entrusted to a person or group. The expression can describe a practical undertaking, such as a delivery or investigation; a religious or humanitarian vocation; the work of an established organization; or an expedition into space. In everyday use, “mission” often conveys commitment and a strong sense of purpose, especially when connected with words such as “humanitarian,” “covert,” or “space.” It can also mean an organization devoted to a particular religious or charitable cause. Although the word is frequently associated with modern military and space programs, its history is older and more general: it originally referred to an act of sending or an appointment given to someone. Understanding that broader sense explains why people speak of professional, educational, or personal missions as well as institutional ones.

This use is less common than the noun and often has a formal or institutional tone.
The plural refers to separate assignments, undertakings, organizations, or spaceflights.

Although “mission” now evokes space travel and humanitarian work, it began with the idea of sending someone on an errand or appointment.

Where does mission come from?
The word entered English through French mission, from Latin missio, an act of sending or an assignment. Latin missio was derived from mittere, “to send,” a root also underlying cognates such as emission, transmission, and submission. Over time, the meaning developed from an act of sending or appointment into the task or purpose assigned to someone.
