D

だぢづでど — The D Row

01

Why the D row?

The D row is the third of the dakuten rows: T row + . It's grammatically heavy. is the plain-form copula ("is / am / are"), ending casual statements (これは本だ, "this is a book"); its polite cousin です replaces だ in formal speech. is one of the most-used particles in Japanese, marking where an action happens (家で食べる, "eat at home") or what tool is used (ペンで書く, "write with a pen"). opens the all-purpose interrogatives どこ (where), どれ (which one), どう (how), どんな (what kind). The two rare characters ぢ and づ sound identical to じ and ず — historical relics, used today only in specific compounds like 鼻血 (hanaji, "nosebleed") and 続く (tsuzuku, "to continue").

Memory trick: T row + ゛ = D row. Workhorses: だ, で, ど. Historical-only: ぢ, づ. When you need a ji or zu sound, default to じ / ず — only reach for ぢ / づ inside compounds where you've seen them spelled that way.

What's next

After the D row, the next dakuten step is the B row (ば び ぶ べ ぼ) — the H row plus ゛. The same H row is also the foundation for the only handakuten row, the P row (ぱ ぴ ぷ ぺ ぽ), where a small circle ゜ replaces the two tick marks. After that, you'll have every basic kana plus every diacritic variant — and the only chapter left is combined kana (きゃ, しゅ, ちょ, etc.).
