Frequently Asked Questions
What are the 4 main tones in Mandarin Chinese Pinyin?
Tone 1 is high-flat (ā), Tone 2 is rising (á), Tone 3 is dipping-falling-rising (ǎ), Tone 4 is sharp-falling (à), and Tone 5 is neutral without an accent mark.
How are tone mark positions determined in Pinyin syllables?
Tones are placed over "a" or "e" if present. In the combination "ou", "o" takes the mark. In other multi-vowel syllables, the second vowel receives the tone mark.
