Katakana Loanwords: 200+ English Words You Already Know in Japanese

How English Becomes Japanese

English words undergo predictable pronunciation changes in Japanese. Consonant clusters get broken up with vowels: "strike" becomes γ‚Ήγƒˆγƒ©γ‚€γ‚― (sutoraiku). Final consonants get a vowel added: "cat" becomes γ‚­γƒ£γƒƒγƒˆ (kyatto). L becomes R: "lemon" becomes レヒン (remon). "Th" becomes s/z: "thank you" becomes ァンキγƒ₯γƒΌ (sankyuu). Long vowels use γƒΌ: "cake" becomes γ‚±γƒΌγ‚­ (keeki).
