A path for anyonewho wants to learn.

Tago helps people start wherever they are, learn for real, and connect one lesson to the next and to lasting ability.

Mission

Help anyone who wants to learn start anywhere without getting lost, learn for real, and keep going.

Vision

Korean learning where one lesson reveals the next connection, and that connection becomes real use and lasting ability.

Tago: ride from what you know to what comes next.

WordSentenceExpressionMy Korean

Look up one word and its example reveals how it is used. Another expression in that sentence becomes the next question.

Tago comes from the Korean phrase 타고 가다—to ride along. It is learning that moves from what you know into the next understanding.

Practise turning Korean you understand into Korean you can use.

Learning happens when you try it yourself. Write and Voca focus on understanding words, expressing your thoughts, and returning to what needs practice.

Understand it in context
Find a word’s meaning and pronunciation, then follow related words in examples to explore how it is used.
Write your own thoughts
Start with a sentence you can write. Reading feedback and revising are part of your own learning.
Come back to remember
Review saved words and return to your writing. Today’s learning becomes the start of your next practice.
