The word is a squeeze of 'web' and 'seminar', so the seminar part is important: it is mostly one-way. Someone is teaching or showing something, and the rest are there to learn. That is what makes it different from a normal video meeting, where everyone talks. A meeting with five people talking freely is not a webinar; it is just an online meeting.

The word is a squeeze of 'web' and 'seminar'這個字是'web'和'seminar'擠在一起造出來的， so the seminar part is important所以seminar（研討會）的部分很重要：it is mostly one-way它大部分是單向的。 Someone is teaching or showing something有人在講解或展示東西， and the rest are there to learn其他人則是來學習的。 That is what makes it different from a normal video meeting這就是它跟一般視訊會議不同的地方， where everyone talks一般視訊會議是大家都會說話。 A meeting with five people talking freely五個人自由交談的會議 is not a webinar不算webinar； it is just an online meeting那只是一場線上會議。

The word belongs to business and education. It sounds a bit formal, the kind of thing that appears on a company email or a poster. Friends do not have a webinar together.

The word belongs to business and education這個字是商業和教育場合用的。 It sounds a bit formal聽起來有點正式， the kind of thing that appears on a company email or a poster是那種會出現在公司email或海報上的用詞。 Friends do not have a webinar together朋友之間不會說要一起"webinar"。

Note also that it is often free but you must sign up first, and many are recorded so you can watch later.
