The Vietnamese alphabet is the foundation of the Vietnamese language, shaping how words are written and spoken. Unlike Chinese, which uses logographic characters, Vietnamese relies on a Roman alphabet with special diacritics and tone marks to indicate pronunciation.
This writing system was developed by French missionaries in the 17th century and officially replaced the Chữ Nôm script after the Vietnam War. Today, the Vietnamese alphabet is closely related to the English alphabet, making it easier for learners to write Vietnamese compared to other Asian languages.
However, the presence of single vowels, vowel combinations, consonant clusters, and different meanings created by tone marks makes Vietnamese pronunciation uniquely challenging. This guide will break down the letters, sounds, and tones of Vietnamese while providing tips to help learners master the Vietnamese language efficiently.
What Is the Vietnamese Alphabet?
The Vietnamese alphabet consists of 29 letters, including:
- 12 vowels (single vowels and vowel combinations)
- 17 consonants (including compound consonant clusters)
- 6 tone marks (acute accent, tilde, grave, hook, dot, and no mark)
This alphabet follows a phonetic system, meaning each vowel letter and consonant has a consistent pronunciation. However, northern Vietnamese and the southern dialect sometimes pronounce the same letter differently, leading to regional variations.
How Many Letters Are in the Vietnamese Alphabet?
Unlike the English alphabet, which has 26 letters, Vietnamese has 29 letters. Notably, F, J, W, and Z are excluded from the Vietnamese alphabet, except in loanwords.
| Category | Letters |
|---|---|
| Vowels | A, Ă, Â, E, Ê, I, O, Ô, Ơ, U, Ư, Y |
| Consonants | B, C, D, Đ, G, H, K, L, M, N, P, Q, R, S, T, V, X |
| Compound Sounds | CH, GH, GI, KH, NG, NGH, NH, PH, QU, TH, TR |
Key Difference: Vietnamese vowels are much more complex than English words because they include diphthongs (two vowel combinations) and triphthongs (three vowel combinations).
Vowels and Consonants in the Vietnamese Alphabet
Vowels: The Core of Vietnamese Pronunciation
Vietnamese has one vowel per syllable but uses vowel combinations to form different sounds.
Single Vowels & Their Pronunciation
| Letter | Pronunciation | Example Word |
|---|---|---|
| A | /aː/ | Ba (father) |
| Ă | /ă/ | Mắt (eye) |
| Â | /ə̆/ | Cẩn (careful) |
| E | /ɛ/ | Mẹ (mother) |
| Ê | /e/ | Kê (chicken) |
| I | /i/ | Đi (go) |
| O | /ɔ/ | To (big) |
| Ô | /o/ | Cô (aunt) |
| Ơ | /ɤ/ | Mở (open) |
| U | /u/ | Bụ (fat) |
| Ư | /ɨ/ | Tư (four) |
| Y | /i/ | Lý (reason) |
Vowel Combinations (Diphthongs & Triphthongs)
Vietnamese uses diphthongs and triphthongs, which are vowel combinations that create blended sounds.
Examples of Diphthongs:
- ai, ao, eo, ia, ôi, ui, ưu, uô
Examples of Triphthongs:
- iêu, oai, ươi, uây
Consonants: Understanding Vietnamese Sounds
Vietnamese has 17 single consonants and 11 compound consonants.
Common Consonant Clusters
- CH – Similar to “ch” in English words like “chat”
- NG / NGH – A nasal sound that is difficult for English speakers
- TH / TR / KH – These are pronounced differently in the northern dialect and southern dialect.
Final Consonants & Optional Beginning Consonants
Unlike English, Vietnamese final consonants are often silent or pronounced softly. Additionally, some syllables in Vietnamese allow for an optional beginning consonant, meaning the sound may or may not be pronounced depending on the word.
The Importance of Diacritics and Tone Marks
One of the biggest challenges when learning Vietnamese is mastering tone marks. Each tone can change the meaning of a word.
Vietnamese Tones & Their Effects on Meaning
| Tone | Mark | Example Word (Ma) | Meaning |
|---|---|---|---|
| Level | No mark | Ma | Ghost |
| Acute | ´ | Má | Mother |
| Grave | ` | Mà | But |
| Hook Above | ˘ | Mả | Tomb |
| Tilde | ~ | Mã | Horse |
| Dot Below | . | Mạ | Rice seedling |
Pronunciation Tip: The hỏi tone (hook) and ngã tone (tilde) are commonly confused, especially by learners unfamiliar with tonal languages.
How to Pronounce Vietnamese Alphabet Letters
Vowel Sounds
- Long and short vowels are taught differently in the northern Vietnamese and southern dialect.
- The same vowel letter can have different words depending on tone.
Consonant Sounds
- Đ vs D: Đ is pronounced as a hard “D,” while D sounds like “Z” in the northern dialect.

History and Evolution of the Vietnamese Alphabet
- Pre-17th Century: Vietnamese was written in Chữ Nôm, which was influenced by Chinese script.
- French Colonisation: Missionaries introduced the Roman alphabet.
- Post-Vietnam War: The Latin-based alphabet became the official writing system.
Common Challenges for Vietnamese Learners
Pronunciation difficulties:
- Ending consonants are often silent or nasal.
- Some tones sound similar, especially in fast speech.
Common spelling mistakes:
- Mixing up diphthongs and single vowels.
- Confusing acute accent with the tilde.
Quick Tips to Master Vietnamese Faster:
- Listen to native speakers daily.
- Practice tones with minimal pairs (e.g., “ma” vs. “má”).
- Use interactive lessons for better retention.
