Questions & Answers about jugyouchuu, nemukute akubi o shite shimaimashita.

What does 授業中 mean, and why is 中 used here?

授業中 means during class or in the middle of class.

Here, 中（ちゅう） means during / in the middle of when attached to a noun.

• 授業 = class, lesson
• 授業中 = during class

This pattern is very common:

• 会議中 = during a meeting
• 仕事中 = while working / during work
• 食事中 = during a meal

So 授業中、 sets the scene: while class was going on.

Why is there a comma after 授業中?

The comma helps separate the time/situation phrase from the main statement.

So the sentence is easier to read as:

• 授業中、 = during class,
• 眠くて = I got sleepy / being sleepy,
• あくびをしてしまいました = I ended up yawning

In Japanese, commas are often used more flexibly than in English. This comma is natural because 授業中 is an introductory phrase.

Why is it 眠くて and not 眠いで or just 眠い?
