+## Tone Sandhi of `不 (bù)`
+
+`不 (bù)` means "no" or "not". When it is followed by a syllable which is in the first, second or the third tone, it remains in the fourth tone.
+
+However, when `不 (bù)` is followed by a syllable which is in the fourth tone, it changes to the second tone.
+
+This tone change is a natural adjustment in speech to make pronunciation smoother.
+
+### Examples
+
+| Written    | Pronounced as |
+|------------|----------------|
+| `bù néng`   | `bù néng`      |
+| `bù xiǎng`   | `bù xiǎng`      |
+| `bù shì`    | `bú shì`       |
