ロケット
ロケット · roketto · JLPT N3 · noun
rocket
🚀 Loanword from English rocket and locket: ro-ket-to = ro + ket + to
Japanese has no L sound, so rocket and locket both come out as roketto. The small ッ doubles the t, and the final o is added because Japanese words rarely end in a consonant. Context tells you which one is meant.
