Korean Sentence Connectors With Billy Go | #16: Thinking & Realizing
There are so many ways to express that you’re “thinking” about something or that you’ve “realized” something, and I’ve compiled the most common and essential ones together into a single lesson. This video covers the forms ~치고(는), ~까 봐(서), ~까, ~보니(까), 치다, ~테니(까), ~텐데, ~고 보니(까), ~다(가) 보니(까), ~다 보니(까), ~다(가) 보면, ~다니, and ~니.
This is a free 20 episode video course all about Korean sentence connectors – grammar that’s used to connect words and sentences to create longer, more natural conversations. Every week I’m uploading a new episode, and this is lesson 16 out of 20.

해요 vs 하는 거예요 (~것이다 Tenses) | Live Class Abridged
In my most recent live stream I taught the differences between ~해요 and ~하는 거예요, and how these differences are part of a larger topic – the form ~것이다. The form ~것이다 can be used to make any tense in Korean – past tense, present tense, and future tense. And there are similarities between all of these forms.

Possessive Marker 의 | Live Class Abridged
My most recent live classroom on Sunday was all about the particle 의, which is used like an apostrophe “s” in English, or like “of.” It’s used to connect two nouns together. I also taught how to use compound nouns together with the 사이시옷, which is the ㅅ that appears at the bottom of a syllable in the middle of a word.

속? 안? What’s INSIDE? | Korean FAQ
Both 안 and 속 mean “inside,” but they’re not used for the same things.
The really quick answer is “use either,” but an even quicker answer is “just use 안.” However, the real answer is a bit longer, and requires knowing what kind of “inside” you’re referring to. Fortunately it’s not difficult, and I explain all of their differences in this 7 minute long episode.

Plurals ~들 ~네 | Live Class Abridged
There’s more than one way to make something plural in Korean, but the most common way is with the Particle 들. This makes any word before it (usually just a noun) into a plural. It can also be used after adverbs, and even phrases, which I also explain.
Another way to make something plural (specifically a person) is with the Particle 네. However, 네 is used differently and is specifically for something that’s a part of a group.
