Tap a card to read the word out loud. Some of them you already know — Vietnamese is your first language, English is your school language. The rest are languages you've heard on trips.
Every two weeks, somewhere in the world, the last person who speaks an old language passes away — and that language goes with them. Languages are like animals: some are common, some are very rare, and once they're gone they're gone.
You speak two languages already — Vietnamese and English. People who speak two languages aren't just twice as good at chatting; their brains literally work differently. Bilingual kids tend to be better at switching between tasks, focusing in noisy rooms, and seeing the world from another person's view.
Every new language you learn is a whole new way of thinking. Free upgrade.
