dakuten; voicing mark
The diacritic ゛ placed on kana to indicate a voiced consonant (e.g., か → が). A fundamental term in Japanese phonology and writing.
「か」に濁点を付けると「が」になります。
Adding a dakuten to か makes it が.
濁点のつく仮名は、が行、ざ行、だ行、ば行です。
Kana with dakuten are the ga, za, da, and ba rows.
handakuten; semi-voiced sound mark
Compound of 濁 (daku, 'muddy, voiced') and 点 (ten, 'point, mark'). The term reflects the traditional description of voiced sounds as 'muddy' or 'impure' in Japanese phonology.
