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 articles to indicate number, case, gender, and a number of other grammatical categories. Meanwhile, the inflectional change of verbs is called conjugation.
A grammatical case is a category of nouns and noun modifiers which corresponds to one or more potential grammatical functions for a nominal group in a wording. In various languages, nominal groups consisting of a noun and its modifiers belong to one of a few such categories. For instance, in English, one says I see them and they see me: the nominative pronouns I/they represent the perceiver and the accusative pronouns me/them represent the phenomenon perceived. Here, nominative and accusative are cases, that is, categories of pronouns corresponding to the functions they have in representation.
Latin declension is the set of patterns according to which Latin words are declined—that is, have their endings altered to show grammatical case, number and gender. Nouns, pronouns, and adjectives are declined, and a given pattern is called a declension. There are five declensions, which are numbered and grouped by ending and grammatical gender. Each noun follows one of the five declensions, but some irregular nouns have exceptions.
Latin is a heavily inflected language with largely free word order. Nouns are inflected for number and case; pronouns and adjectives are inflected for number, case, and gender; and verbs are inflected for person, number, tense, aspect, voice, and mood. The inflections are often changes in the ending of a word, but can be more complicated, especially with verbs.

Standard Romanian shares largely the same grammar and most of the vocabulary and phonological processes with the other three surviving varieties of Balkan Romance, namely Aromanian, Megleno-Romanian, and Istro-Romanian.
Swedish is descended from Old Norse. Compared to its progenitor, Swedish grammar is much less characterized by inflection. Modern Swedish has two genders and no longer conjugates verbs based on person or number. Its nouns have lost the morphological distinction between nominative and accusative cases that denoted grammatical subject and object in Old Norse in favor of marking by word order. Swedish uses some inflection with nouns, adjectives, and verbs. It is generally a subject–verb–object (SVO) language with V2 word order.
The grammar of Old English is quite different from that of Modern English, predominantly by being much more inflected. As an old Germanic language, Old English has a morphological system that is similar to that of the Proto-Germanic reconstruction, retaining many of the inflections thought to have been common in Proto-Indo-European and also including constructions characteristic of the Germanic daughter languages such as the umlaut.
The grammar of the Polish language is characterized by a high degree of inflection, and has relatively free word order, although the dominant arrangement is subject–verb–object (SVO). There commonly are no articles, and there is frequent dropping of subject pronouns. Distinctive features include the different treatment of masculine personal nouns in the plural, and the complex grammar of numerals and quantifiers.
Romanian nouns, under the rules of Romanian grammar, are declined, varying by gender, number, and case.
The nouns of the German language have several properties, some unique. As in many related Indo-European languages, German nouns possess a grammatical gender; the three genders are masculine, feminine, and neuter. Words for objects without obvious masculine or feminine characteristics like 'bridge' or 'rock' can be masculine or feminine. German nouns are declined depending on their grammatical case and whether they are singular or plural. German has four cases: nominative, accusative, dative and genitive.
German articles are used similarly to the English articles, a and the. However, they are declined differently according to the number, gender and case of their nouns.
The Dutch language in its modern form does not have grammatical cases, and nouns only have singular and plural forms. Many remnants of former case declensions remain in the Dutch language, but few of them are productive. One exception is the genitive case, which is still productive to a certain extent. Although in the spoken language the case system was probably in a state of collapse as early as the 16th century, cases were still prescribed in the written standard up to 1946/1947. This article describes the system in use until then. For a full description of modern Dutch grammar, see Dutch grammar. See also History of Dutch orthography.
Icelandic is an inflected language. Icelandic nouns can have one of three grammatical genders: masculine, feminine or neuter. Nouns, adjectives and pronouns are declined in four cases and two numbers, singular and plural.
Gothic is an inflected language, and as such its nouns, pronouns, and adjectives must be declined in order to serve a grammatical function. A set of declined forms of the same word pattern is called a declension. There are five grammatical cases in Gothic with a few traces of an old sixth instrumental case.
Old Norse has three categories of verbs and two categories of nouns. Conjugation and declension are carried out by a mix of inflection and two nonconcatenative morphological processes: umlaut, a backness-based alteration to the root vowel; and ablaut, a replacement of the root vowel, in verbs.
Old High German is an inflected language, and as such its nouns, pronouns, and adjectives must be declined in order to serve a grammatical function. A set of declined forms of the same word pattern is called a declension. There are five grammatical cases in Old High German.
The Colognian declension system describes how the Colognian language alters words to reflect their roles in Colognian sentences, such as subject, direct object, indirect object, agent, patient, etc. Declension allows speakers to mark nouns as being used in their different roles – whether as subjects, direct objects, indirect objects, possessives, etc. – by changing the form of the noun plus any associated adjectives or articles instead of indicating this meaning through word order or prepositions. Still, Colognian generally makes only limited use of word order; shifting words around either does not alter the meanings of sentences, or yields other types of sentences which have different meanings yet still maintain the roles of the referents of the words as long as their declined forms are kept.
The grammar of Old Saxon is highly inflected, similar to that of Old English or Latin. As an ancient Germanic language, the morphological system of Old Saxon is similar to that of the hypothetical Proto-Germanic reconstruction, retaining many of the inflections thought to have been common in Proto-Indo-European and also including characteristically Germanic constructions such as the umlaut. Among living languages, Old Saxon morphology most closely resembles that of modern High German.
This article describes the grammar of the Old Irish language. The grammar of the language has been described with exhaustive detail by various authors, including Thurneysen, Binchy and Bergin, McCone, O'Connell, Stifter, among many others.
