Declension

Inflection of words according to number, gender, and/or case

In linguistics, declension is the changing of the form of a word, generally to express its syntactic function in the sentence, by way of some inflection. Declensions may apply to nouns, pronouns, adjectives, adverbs, and determiners to indicate number, case, gender, and a number of other grammatical categories. Meanwhile, the inflectional change of verbs is called conjugation.
