Webinar is a portmanteau word I hear every weekday morning. Every time I turn on GoToWebinar, I hear, “Welcome to the Webinar.”
A webinar is an online presentation. The word is a combination of “World Wide Web” and “seminar.”
Web is from the Old English word webb. Webb meant woven fabric or tapestry.
Seminar comes ultimately from the Latin word for seed. In Latin, a seminarium was a plant nursery. A seminar was once thought of as a “breeding ground” for ideas.
