逗号,

Comma serves the function of separating parts in a sentence. The European form of the comma developed from the symbol / which was previously used for a similar purpose. The English name 「comma」 is derived from the Greek word κόμμα, meaning 「cut-off」 or 「short sentence.」 Commas first appeared in Russian texts in the 1520s.

Other symbols that function as commas include ̕ , ⸲ , ⸴ , and ⹁ .
