  • Two trees

    • Nature
    • JLPT N2
    • 木き / kitree
    • 林はやし / hayashigrove / small woodland

    StructureHow the kanji is literally written.

    Two trees side by side suggest a little woodland! The kanji is literally written with two 木.

    Repeating a component is a traditional way of suggesting “many” or “a group”. It is how these particular kanji are built, not a rule that adding meanings explains every kanji.

  • Three trees

    • Nature
    • JLPT N2
    • 木き / kitree
    • 森もり / moriforest

    StructureHow the kanji is literally written.

    Three trees suggest a whole forest! The kanji is literally written with three 木.

    Three copies suggest “a great many” trees. Japanese usually uses 森 for a bigger, denser wood than 林, though the line between them is not strict.

  • Younger sister

    • Family
    • JLPT N4
    • 女おんな / onnawoman
    • 未み / minot yet
    • 妹いもうと / imōtoyounger sister

    Memory aidA story to help you remember, not the real history.

    Picture a girl (女) who is “not yet” (未) grown up: a younger sister.

    This is a memory story, not the real history of the kanji. Many kanji combine a meaning part and a sound part, and 未 (ミ) is generally explained as the sound part of 妹 (マイ), not as “not yet”.
