One rule cuts the choices

After p, t, c or ch, only two tones exist. Vietnamese accent marks explained shows how to use it, and the spelling rules handle the letters.

Quick answers

Why do so many Vietnamese words look alike?

Vietnamese is built from syllables, and many everyday words are a single one. The tone marks and the letter marks (hat, horn, breve, the bar of đ) are what tell them apart.

What is the most famous example?

Ma, mà, má, mả, mã, mạ: the same letters with each of the six tones, and six different words.

How do I stop mixing them up?

Read the marks first, then link each one to the sound you already hear. One known word per rhyme helps: it fixes the spelling to a sound you know.
