Symbol ゞ

The symbol “ゞ” in Japanese, known as the iteration mark, is used to denote the repetition of the previous hiragana character with the addition of a voiced sound (dakuten). It functions as a repetition mark but modifies the character to its voiced form. For instance, in the case of the word “いすゞ” (Isuzu), the “ゞ” repeats and voices the preceding hiragana. This symbol is part of a group of characters called “odori-ji” or “repetition marks” in Japanese writing.

However, it’s important to note that in modern Japanese, the use of “ゞ” and other repetition marks like “ゝ” is not common. These characters are more likely to be found in classical texts or specific traditional contexts, and in everyday writing, direct repetition of characters is generally preferred.
