What does 인터넷에서 본 광고 mean literally, and why is 본 before 광고?

It literally means something like the advertisement seen on the internet.

Korean puts a modifying clause before the noun it describes. So:

• 인터넷에서 = on the internet / from the internet
• 본 = saw / seen
• 광고 = advertisement

So instead of saying the ad that I saw on the internet, Korean says on-the-internet saw ad.

Here, 본 is the noun-modifying form of 보다 (to see).

Why is 에서 used in 인터넷에서, not 에?

Because 에서 usually marks the place where an action happens.

In this sentence, the action is seeing the ad, so Korean treats the internet as the place/source where you saw it:

• 인터넷에서 본 광고 = the ad seen on the internet

Using 에 here would sound unnatural, because 에 is more often used for location/existence/direction, while 에서 is commonly used for actions.

A useful comparison:

• 학교에 있어요 = It is at school.
• 학교에서 공부해요 = I study at school.

Likewise:

• 인터넷에서 봤어요 = I saw it on the internet.

What exactly is 본, and how is it related to 보다?
