HIRAGANA · MAIN KANA
wo
を · paired with ヲ
Sound and use
In modern standard Japanese, the object particle を is usually pronounced o; wo remains its conventional romanization.
See ヲ, the katakana counterpart →
Kana represent sounds and spelling functions. They do not have lexical meanings of their own.
How the shape formed
The standard hiragana shape is conventionally traced to a cursive form of 遠. Earlier manuscripts also used other shapes for the same sound.
History and change
Japanese writers used Chinese characters for their sounds. The source character 遠 belonged to that wider practice; the kanji meaning was not inherited by を.
Hiragana and katakana developed as Japanese syllabaries in the early Heian period (794–1185). This is the script-level period, not a first attested date for を.
In modern standard Japanese, the object particle を is usually pronounced o; wo remains its conventional romanization.
What is documented?
The sources above support the script’s broad period and the conventional parent-character account for を. A first surviving appearance of this exact modern shape has not been established for this entry.
