A few symbols whose meaning is unclear have been retained directly, as given in Boas. These include V and v. The symbol -" corresponds to a special symbol in the original chart (a dash with trema); its meaning is also unclear. A few corrections to the original chart are made in the version above. Class 2 suffixes are listed in this chart as "all -", i.e. lengthening all stems. However, all the class 2 suffixes described by Boas which productively apply to roots of type B or C leave stems unchanged rather than triggering lengthening. This also adheres to the phonotactics of Kwakʼwala, which do not allow super-heavy syllables of the type which would be created by lengthening these stems.
