Phonetic transliteration of "Vashti" or "Vasti":
瓦 (wǎ) catches the V/W sound,
思 (sī) for "-sh-,"
弟 (dì) for "-ti." Vashti is best known as the queen in the Book of Esther; the name resurfaces in subtitled drama. The characters individually mean "tile / think / younger brother" — sound only, no semantic content.
