Cherokee has a robust tonal system in which tones may be combined in various ways, following subtle and complex tonal rules that vary from community to community. While the tonal system is undergoing a gradual simplification in many areas (no doubt as part of Cherokee's often falling victim to second-language status), the tonal system remains extremely important in meaning and is still held strongly by many, especially older speakers.
