21 Tone Sandhi (Tone Changes in Context)

We are going to learn tone sandhi rules and words or phrases.

  • Common tone sandhi rules in Mandarin.
  • Examples of tone sandhi in words and phrases.
    • Tone 3 Sandhi: When two third tones are together, the first one often changes to a second tone (e.g., nǐ hǎo -> ní hǎo).
    • Third Tone Sandhi (三声变调):

This rule applies to consecutive third-tone syllables, especially in pairs.

In longer sequences (e.g., three or more third tones), native speakers often apply this rule in chunks, following prosodic grouping.

  • “不” (bù) Sandhi:

When 不 (bù) is followed by a fourth tone (ˋ), bù changes to second tone (bú).

  • bù yào (不要) → bú yào

  • bù shì (不是) → bú shì

If followed by any tone other than the fourth, remains fourth tone.

  • “一” (yī) Sandhi

When 一 (yī) is followed by a fourth tone, it changes to second tone (yí).

  • yī bàn (一半) → yí bàn

When 一 (yī) is followed by a first, second, or third tone, it changes to fourth tone (yì).
