ど

• IPA^(key): [do̞]

The hiragana character と (to) with a dakuten (゛).

ど (romaji do)

1. The hiragana syllable ど (do). Its equivalent in katakana is ド (do).

• (Hiragana) 平仮名; あぁ, いぃ, うぅゔ, えぇ, おぉ, かゕが, きぎ, くぐ, けゖげ, こご, さざ, しじ, すず, せぜ, そぞ, ただ, ちぢ, つっづ, てで, とど, な, に, ぬ, ね, の, はばぱ, ひびぴ, ふぶぷ, へべぺ, ほぼぽ, ま, み, む, め, も, やゃ, ゆゅ, よょ, ら, り, る, れ, ろ, わゎ, ゐ, ゑ, を, ん, ー, ゝ, ゞ, ゟ

Appears to be a relatively recent innovation. In mainstream Japanese, this prefix is used as an intensifier. In the Kansai region, the meaning has further developed to convey more negative overtones.[1][2]

The ultimate derivation is unclear. This may be an extension of the noun 度 (do, “degree, extent”).
