Vietnamese uses the Latin alphabet, which makes it look approachable at first glance. But between extra letters, diacritics, and six tones, reading it fluently takes more than knowing your ABCs.
The 29-Letter Alphabet
Vietnamese drops four letters you'd expect from the standard Latin alphabet (F, J, W, Z — they only appear in loanwords) and adds seven of its own, built from a base letter plus a diacritic: ă, â, đ, ê, ô, ơ, ư.
That gives a total of 29 letters: a, ă, â, b, c, d, đ, e, ê, g, h, i, k, l, m, n, o, ô, ơ, p, q, r, s, t, u, ư, v, x, y.
Why the Extra Letters Exist
Each diacritic-marked letter represents a distinct vowel sound that the plain Latin letter can't capture on its own:
- ă is a short version of "a"
- â and ê use a circumflex for a different vowel quality than their plain counterparts
- ơ and ư use a hook to represent vowel sounds with no direct equivalent in English
- đ is a consonant, not a vowel: it's pronounced like an English "d," while plain d sounds more like "z" or "y" depending on the dialect
Mixing up đ and d is one of the most common early mistakes, since they look almost identical but sound completely different.
The 6 Tones
Every Vietnamese syllable carries one of 6 tones, and the tone is just as essential to the word's identity as the letters are:
- ngang (level) — no tone mark, a flat mid pitch
- huyền (falling) — a grave accent, pitch falls
- sắc (rising) — an acute accent, pitch rises sharply
- hỏi (dipping-rising) — a hook above, pitch dips then rises
- ngã (creaky rising) — a tilde, pitch rises with a glottal catch
- nặng (heavy) — a dot below, a short, low, heavy pitch
Change only the tone on a word and you change its meaning entirely — this is true of every tonal language, and Vietnamese is no exception.
Regional Pronunciation Differences
Vietnamese has three major dialect regions — Northern (Hanoi), Central (Huế), and Southern (Ho Chi Minh City) — and they pronounce some letters and tones differently. Most notably, the hỏi and ngã tones merge into one in Central and Southern Vietnamese, while Northern Vietnamese keeps them distinct. The written form, including which tone mark a word uses, stays the same everywhere; only the pronunciation shifts.
If you're just starting out, learning Northern (Hanoi) pronunciation first is the standard recommendation, since it's used in official media and education.
A Practical Learning Order
- Learn the 22 letters shared with the Latin alphabet first — their sounds are closest to what you already know
- Add the 7 diacritic letters one at a time, starting with â/ê (circumflex) before ơ/ư (hook), since the circumflex pair sounds closer to familiar vowels
- Learn ngang and sắc first among the tones — a flat tone and a clearly rising tone are the easiest contrast to hear
- Add the remaining four tones gradually, listening for the pitch shape rather than trying to produce them from a written description alone

What's Next?
Vietnamese shares its Latin-based writing with few other languages in Asia, which makes the script itself approachable — the real work is tones and the diacritic vowels. Once those feel natural, reading Vietnamese text becomes mostly a vocabulary problem rather than a decoding problem.
Note for readers: This guide is in draft while we confirm its linguistic claims, particularly around regional tone mergers. If anything looks off, we'd welcome the correction.
