Number is not marked in most nouns, but is marked in certain cases in verbs. Relationship nouns do have a plural in with (or for many speakers ), e.g. "my grandfathers".As seen in this example, the suffix takes high tone after a low-tone stem. Also note that the suffix 'one's own' disappears after this suffix. See A few verbs have suppletive plural forms, as in many other North American languages. In addition, Haida has a plural verb suffix (Skidegate) (Masset) / (Kaigani) that is used to indicate that some third person pronoun in the sentence is plural, and to mark plural subject in imperatives. The third person pronoun that is pluralized can have any grammatical function, e.g. "I bought all their fish" (Masset).
