Hindi: spelling → sound
Hindi asks the ear for a distinction English does not make, and makes it twice. Every stop comes in four versions: plain, aspirated, voiced, and BREATHY-voiced — क ख ग घ, ka kha ga gha. And it runs that four-way set across two places English merges into one: dental त (tongue on the teeth) and retroflex ट (tongue curled back to the roof). Sixteen consonants where English has four. Breathy voice is not aspiration: the folds stay slack and keep vibrating through the puff, which is why भ is not just a loud ब. The tracer here reads the ROMANISATION, not the Devanagari — but Devanagari is worth learning early, because unlike English it spells exactly what it means.
Trace a word
Every box is one rule firing. Hover a box (or open the table) to see why. Rules are applied in order, first match wins — that order is the spelling system. Type the romanisation (namaste, paani) — the tracer reads that, not the Devanagari.
Consonants & glides
| IPA | Spelled | Example |
|---|---|---|
| k | k, क | kaam kaːm work |
| kʰ | kh, ख | khaanaa kʰaːnaː food — A puff of air. kaam 'work' vs khaam 'raw'. |
| ɡ | g, ग | garam ɡəɾəm hot |
| ɡʱ | gh, घ | ghar ɡʱəɾ house — Breathy, not aspirated — voicing carries on through the breath. |

| dʱ | dh, ध | dhuup dʱuːp sunshine |
| ʈ | ṭ, ट | ṭamaaṭar ʈəmaːʈəɾ tomato — RETROFLEX: tongue curled back. This is the one English speakers substitute for both — English t sits between the two and sounds foreign either way. |
