How do Inuit nouns show singular, dual, and plural number?

In Inuit languages, nouns indicate singular, dual, and plural number through the use of suffixes. These grammatical numbers are often accompanied by changes in the word stem, such as the doubling of consonants or other vowel and consonant alternations.1

For example, the singular noun nanuq (polar bear) becomes nannuk in the dual form (two polar bears) and nannut in the plural (several polar bears). Similarly, the singular inuk (person) becomes innuk in the dual and inuit in the plural.1

These number markers can also combine with other suffixes to indicate possession. For instance, in Inupiaq, the singular ulu-ga (my knife) contrasts with the plural ulu-t-ka (my knives), where the suffix -t- denotes plurality and -ga or -ka indicates the possessor.1
