An agglutinative language is a type of synthetic language with morphology that primarily uses agglutination. Words may contain different morphemes to determine their meanings, but all of these morphemes (including stems and affixes) remain, in every aspect, unchanged after their unions. This results in generally more easily deducible word meanings if compared to fusional languages, which allow modifications in either or both the phonetics or spelling of one or more morphemes within a word. This usually results in a shortening of the word, or it provides easier pronunciation.


Agglutinative languages have generally one grammatical category per affix while fusional languages have multiple. The term was introduced by Wilhelm von Humboldt to classify languages from a morphological point of view. It is derived from the Latin verb ''agglutinare'', which means "to glue together". Non-agglutinative synthetic languages are fusional languages; morphologically, they combine affixes by "squeezing" them together, drastically changing them in the process, and joining several meanings in a single affix (for example, in the Spanish word ''comí'' "I ate", the suffix -''í'' carries the meanings of first person, singular number, past tense, perfective aspect, indicative mood, active voice.) The term ''agglutinative'' is sometimes incorrectly used as a synonym for synthetic, but that term also includes fusional languages. The agglutinative and fusional languages are two ends of a continuum, with various languages falling more toward one or the other end. For example, Japanese is generally agglutinative, but displays fusion in some nouns, such as , from oto+hito (originally woto+pito), and Japanese verbs, adjectives, the copula, and their affixes undergo sound transformations. For example, affixed with and becomes . 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). Agglutinative languages tend to have a high rate of affixes or morphemes per word, and to be very regular, in particular with very few irregular verbs. For example, Japanese has very few irregular verbs – only two are significantly irregular, and there are only about a dozen others with only minor irregularity; Luganda has only one (or two, depending on how "irregular" is defined); while in the Quechua languages, all the ordinary verbs are regular. Korean has only ten irregular forms of conjugation except for the passive and causative conjugations. Georgian is an exception; it is highly agglutinative (with up to eight morphemes per word), but it has a significant number of irregular verbs with varying degrees of irregularity.


Examples of agglutinative languages include: *Indigenous languages of the Americas **Algonquian languages ***Cree (also classified as polysynthetic) ***Blackfoot (partially fusional) **Siouan languages ***Lakota ***Yuchi **Athabaskan languages **Muskogean languages **Quechuan languages **Aymaran languages **Tupian languages **Araucanian languages **Salishan languages **Mesoamerican languages ***Nahuatl ***Wasteko *Austronesian languages **Tagalog **Malay **Indonesian **Javanese *Niger–Congo languages **Bantu languages **Igboid languages *Berber languages *Dravidian languages **Tamil **Kannada **Telugu **Malayalam **Tulu *Eskimo–Aleut languages **Aleut **Inuktitut **Yupik *Turkic languages **Turkish **Azerbaijani **Uzbek **Kazakh **Uyghur **Turkmen **Kyrgyz **Tatar **Yakut **Bashkir **Chuvash *Tungusic languages *Japanese *Korean *Mongolic languages **Mongolian language **Kalmyk language **Buryat language **Moghol language **Oirat language **Khamnigan language *Languages of the Caucasus **Kartvelian languages **Northwest Caucasian languages **Northeast Caucasian languages *Tibeto-Burman languages **Tibetan (both Classical and Standard) **Mizo **Lai *Uralic languages **Sámi languages **Hungarian **Finnish **Estonian *Basque *Munda languages **Santali Many languages spoken by Ancient Near East peoples were agglutinative: * Elamite * Hattic * Kassite * Lullubi *Sumerian language Some well known constructed languages are agglutinative, such as Esperanto, Klingon, Quenya and Black Speech. Agglutination is a typological feature and does not imply a linguistic relation, but there are some families of agglutinative languages. For example, the Proto-Uralic language, the ancestor of the Uralic languages, was agglutinative, and most descended languages inherit this feature. But since agglutination can arise in languages that previously had a non-agglutinative typology and it can be lost in languages that previously were agglutinative, agglutination as a typological trait cannot be used as evidence of a genetic relationship to other agglutinative languages. The uncertain theory about Ural-Altaic proffers that there is a genetic relationship with this proto-language as seen in Finnish, Mongolian and Turkish.Nicholas Poppe, The Uralo-Altaic Theory in the Light of the Soviet Linguistics
Accessed 2010-04-07 Many languages have developed agglutination. This developmental phenomenon is known as language drift. There seems to exist a preferred evolutionary direction from agglutinative synthetic languages to fusional synthetic languages, and then to non-synthetic languages, which in their turn evolve into isolating languages and from there again into agglutinative synthetic languages. However, this is just a trend, and in itself a combination of the trend observable in Grammaticalization theory and that of general linguistic attrition, especially word-final apocope and elision.
