The sound system of Quechan is different from the sound system of English. This dictionary is written using a practical writing system developed in the 1990s with the help of Quechan elders. Each of the symbols below represents a sound of the language. Some symbols consist of a single letter, like k, and some symbols are two or three letters long, for instance, th and kw are two-letter symbols, and lly is a three-letter symbol.

Most Quechan verbs usually take at least one suffix. In the
with a neutral suffix: -
k or -m, depending on the verb. A hyphen separates the suffix from the verb stem, and when you see a hyphen, you know that the suffix is removable. When -k or -m is removed, another suffix or a series of suffixes may replace it.
