ELI5: Explain Like I'm 5

Topic marker

Okay kiddo, today we are going to learn about something called a "topic marker". Do you remember when we talk about a certain thing or person and we add the word "about" before it to show that we are talking about that thing or person? Well, a topic marker in some languages is like that "about" word.

In some languages, like Japanese or Korean, they have a special word that goes at the end of a sentence to show what the sentence is about. It's like a special mark that tells us what the most important thing in the sentence is. Let's say we're talking about a dog. In Japanese, we'd say "Inu wa..." which means "As for the dog..." and then we'd say something about the dog.

The topic marker helps us know what the conversation is about and what the main focus is. It can also help us understand the meaning of the sentence better. It's like a signpost that shows us where to pay the most attention.

So, the next time you hear someone use a word at the end of a sentence that sounds like "wa" or "ga" in Japanese or "neun" or "eun" in Korean, you'll know they're using a topic marker to show the focus of the sentence. Cool, huh?
