Fullwidth Semicolon

In Chinese text, it separates closely related clauses. It often divides parallel clauses or major sentence parts, with a pause stronger than a comma but shorter than a full stop.

Read it through the surrounding sentence. In ordinary English prose, the narrow ASCII form ; is usually expected.

How did fullwidth semicolon history unfold?

It took shape as punctuation was fitted to East Asian text cells. The semicolon appears in European printing by the late fifteenth century. East Asian typography later fitted Western punctuation into fixed character cells, and older character sets kept wide forms for compatibility.

Classical Chinese used reader-added dots and sentence markers. The key dates are 1869, 1919, and 1920: a book explained Western punctuation, reformers proposed a modern set, and an education order followed. The semicolon belongs to modern punctuation, not an ancient Chinese rule.

Japan took a different route. In the 1590s, a Jesuit press tried European punctuation but favored commas and full stops. Western influence grew in the Meiji period, and fiction in the mid-1880s helped punctuation spread.

Why is ； wider than ;?

Because it fills a full East Asian character cell. The ASCII semicolon is narrow; this character takes a full-width cell. They have the same punctuation role but are separate characters.
