For Life

Hi! Nice to have you back in the family!

You may think you already know how to use these words, but take a closer look!

Today's LessonCATEGORY: Problem Vocabulary


  • Your brother is a boy or man with the same parents as you.

    Your sister is a girl or woman with the same parents as you.

    Be careful:
    The Japanese words for brother and sister actually mean "older" or "younger" brother or sister. In English, this difference becomes less important. Normally, you just say brother or sister unless you need to make clear which brother or sister you're talking about to avoid confusion.
  • brother  は、自分と同じ両親を持つ男子、つまり、兄または弟という意味です。

    sister  は、自分と同じ両親を持つ女子、つまり、姉または妹という意味です。

    日本語では兄、弟、姉、妹のように、どちらが年上かがはっきりしていますが、英語ではこのような年齢の違いをそれほど重要視していません。年齢順をよっぽどはっきりさせたいとき意外は単に brother  または sister  と言うのが普通です。
