Why Katakana Loanwords Are Your Secret Weapon
Here’s a fact that often surprises beginners: as an English speaker learning Japanese, you already “know” thousands of Japanese words. Japanese has borrowed extensively from English, and many of these loanwords (外来語, gairaigo) are written in katakana.
Once you can read katakana, you unlock an enormous vocabulary shortcut. A word like コンピューター (konpyuutaa) looks exotic, but it’s just “computer” in Japanese pronunciation.
How English Becomes Japanese: The Sound Rules
English sounds get adapted to fit Japanese phonology. Knowing these patterns helps you decode loanwords faster:
| English pattern | Japanese adaptation | Example |
|---|---|---|
| Final consonant (e.g., -t, -k) | Add ト, ク (to, ku) | market → マーケット |
| -tion, -sion | ション (shon) | station → ステーション |
| Long vowels | ー (long vowel mark) | door → ドア / beer → ビール |
| -er, -or (at end) | ー | computer → コンピューター |
| -ing | ング (ngu) | running → ランニング |
| v sound | ヴ or バ/ビ/ブ/ベ/ボ | video → ビデオ |
| th sound | ス or ズ | three → スリー |
