The term was introduced by Wilhelm von Humboldt to classify languages from a morphological point of view.
[2] For example, the English word antidisestablishmentarianism can be broken up into anti- "against", dis- "to deprive of", establish (here referring to the formation of the Church of England), -ment "the act of", -arian "a person who", and -ism "the ideology of".
For example, Japanese is generally agglutinative, but displays fusion in some nouns, such as otōto (弟, "younger brother"), from oto + hito (originally woto + pito, "young, younger" + "person"), and Japanese verbs, adjectives, the copula, and their affixes undergo sound transformations.
For example, kaku (書く, "to write; [someone] writes") affixed with masu (ます, politeness suffix) and ta (た, past tense marker) becomes kakimashita (書きました, "[someone] wrote", with the -mas- portion used to express a politely distanced social context to the intended audience).
A synthetic language may use morphological agglutination combined with partial usage of fusional features, for example in its case system (e.g., German, Dutch, and Persian).
Persian has some features of agglutination, making use of prefixes and suffixes attached to the stems of verbs and nouns.
Turkish is generally agglutinative, forming words in a similar manner: araba (car) + lar (plural) + ın (possessive suffix, performing the same function as "of" in English) + a (dative suffix, for the recipient of an action, like "to" in English) forms arabalarına (lit.
The uncertain theory about Ural-Altaic proffers that there is a genetic relationship with this proto-language as seen in Finnish, Mongolian and Turkish,[7] and occasionally as well as Manchurian, Japanese and Korean.
