These words form part of the Japanese language too
It's so useful when a word in another language is the same in your own language! Perhaps it sounds exactly the same. 'Taxi' is a good example of a very international word that is similar in many languages. In English, we use many french words as part of our normal vocabulary due to our historic connection and use of French. Words like: rendezvous and aide de camp for example.
他の言語と自分の言語に同じ言葉があると便利ですよね。同じように聞こえることでしょう。タクシーは、多くの言語で使われる世界共通の言葉となっているのがいい例です。英語では、歴史的背景からフランス語を使っていたので、語彙の中にたくさんのフランス語があります。rendezvous（待ち合わせ）や aide de camp（副官）などがその例です。
