Suffixation in the context of "Derivation (linguistics)"

Central Alaskan Yupʼik (also rendered Yupik, Central Yupik, or indigenously Yugtun) is one of the languages of the Yupik family, in turn a member of the Eskimo–Aleut language group, spoken in western and southwestern Alaska. Both in ethnic population and in number of speakers, the Central Alaskan Yupik people form the largest group among Alaska Natives. As of 2010 Yupʼik was, after Navajo, the second most spoken aboriginal language in the United States. Yupʼik should not be confused with the related language Central Siberian Yupik spoken in Chukotka and St. Lawrence Island, nor Naukan Yupik likewise spoken in Chukotka.

Yupʼik, like all Eskimo languages, is polysynthetic and uses suffixation as primary means for word formation. There are a great number of derivational suffixes (termed postbases) that are used productively to form these polysynthetic words. Yupʼik has predominantly ergative alignment: case marking follows the ergative pattern for the most part, but verb agreement can follow an ergative or an accusative pattern, depending on grammatical mood. The language grammatically distinguishes three numbers: singular, dual, and plural. There is no marking of grammatical gender in the language, nor are there articles.

Latin declension is the set of patterns in the Latin language for how nouns and certain other parts of speech (including pronouns and adjectives) change form according to their grammatical case, number and gender. Words that change form in this manner are said to be declined.

Declension is normally marked by suffixation: attaching different endings to the declined word. For nouns, Latin grammar instruction typically distinguishes five main patterns of endings. The patterns are numbered from first to fifth and subdivided by grammatical gender. The term "declension" can refer either to the overarching phenomenon, or to one of these specific five patterns. For example, nouns that have a genitive singular form that ends in -ae are said to belong to "the first declension".
