Definition of the word engage in

The word "engage" originates from the Old French "engagier," meaning "to fasten, to bind." It eventually evolved into the Middle English "engeagen," which meant "to provide with weapons, to arm." In the 16th century, the term "engage" came to mean "to enter into battle or conflict," usually in a military context. The phrase "engage in" originated in the 17th century as an English idiom, combining the meaning of the verb "engage" with the preposition "in." This expression indicates that someone is participating in an activity or action, usually a voluntary one, and takes on its full responsibility. Over time, the meaning of "engage in" broadened to encompass non-military contexts, such as employment, academic studies, or hobbies, and has become a commonly used phrase in contemporary English.
