What is wasei-eigo?
Wasei-eigo are Japanese words that look English but don't work in English, or mean something else. For example, an English “mansion” is a huge, luxurious house. A normal one is an “apartment” (or a “condo” in the US, if it's owned).
I live in an apartment near the station.
駅の近くのマンションに住んでいます。
Wow, his parents live in a mansion!
わあ、彼の両親は大豪邸に住んでるんだ!
💡 Tomo's tip: Before using a katakana word in English, pause and ask: is this really English?
