Pick a course.

Start here if you cannot read Korean yet. All 40 letters, four or five a day, each with its sound, a memory hook drawn from the letter's own design, stroke order and two goes at writing it. Then two days on reading whole words. Hangul was designed to be learned quickly, and it is.

One short lesson a day covering the phrases you would actually use: hello and thank you, your name, ordering food, prices, directions and plans. Each day explains why the Korean works the way it does, then quizzes you.

For anyone who can read Hangul and still cannot follow it spoken. Korean spelling shows what a word is made of, and the sounds change where the blocks meet. Ten days, one family of changes each, every one shown as the spelling beside what is actually said.

Korean counts in two systems at once, one borrowed from Chinese and one native, and uses both in the same phrase to tell the time. Twenty days on the two sets, money, time and dates, ages, counters, phone numbers and the very big numbers, where Korean groups by ten thousand.

Polite, practical Korean for eating in Korea: getting a table, ordering, table manners, barbecue, paying, cafes, markets, street food, convenience stores and delivery, with the etiquette explained as you go.

The Korean of fandom and drama: fan words, reactions, the titles people call each other, casual speech, love lines and arguments, and the slang in the comments. Every line is written for the lesson, and each one says whether it is safe to use in real life.

A reading course for webtoons in Korean: how a vertical scroll is laid out, casual dialogue as it is written in bubbles, the sound and feeling words drawn into the panels, the genres and their vocabulary, and a method for reading on your own.

A listening course for variety and reality TV: the reactions, the teasing, the games and forfeits, the on-screen captions, and fast casual speech. It also says plainly which of it would be rude off screen.
