The Nepali Alphabet

What kind of writing system this is

Devanagari is not an alphabet in the strict sense. It is an abugida: every consonant carries a built-in a sound, and other vowels are written as marks attached to it.

So क is not k — it is ka. To get ki you add a mark: कि. To get a bare k with no vowel at all you add a halant underneath: क्. This is the single most important thing to understand, and it explains almost every apparent oddity in the script.

The twelve vowels

The left column is the independent form, used at the start of a word. The second column shows the same vowel attached to a consonant. You need both.

The thirty-six consonants

The order is phonetic. Consonants are grouped by where in the mouth they are produced, moving from the back of the throat forward to the lips. Within each group the order is: unvoiced, unvoiced aspirated, voiced, voiced aspirated, nasal.

The retroflex and dental rows are the pair English speakers struggle with most. ट and त both sound like t to an untrained ear, but they are entirely different letters and swapping them changes the word.

The line across the top

The horizontal stroke running along the top of a word is the shirorekha, literally the head-line. It is not decoration. It marks where one word ends and the next begins, which matters in a script that historically did not always use spaces.

When letters join into a conjunct — क + ष becoming क्ष — the shirorekha runs unbroken across the whole cluster. That continuity is how a reader knows the letters belong together.

How to practise

Learn the vowels first, both forms, because you cannot write anything without them. Then take the consonant groups one row at a time rather than in bulk; the phonetic ordering means each row shares a mouth position and they reinforce each other.

Use the Nepali typing tool to check yourself: type what you think the romanization is and see whether the Devanagari matches what you intended.
