An agglutinative language is a type of synthetic language with morphology that primarily uses agglutination: words may contain different morphemes to determine their meaning, but each of these morphemes (including stems and affixes) remains in every aspect unchanged after their union, thus resulting in generally easier 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, generally for shortening the word on behalf of an 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
