agglutination

In contemporary linguistics, agglutination usually refers to the kind of morphological derivation in which there is a one-to-one correspondence between affixes and syntactical categories. Languages that use agglutination widely are called agglutinative languages. For example, the Hungarian word hajókon `on ships' may be divided into a root hajó with two endings -k and -on expressing respectively the plural number (hajó-k `ships') and the location `on' something (hajó-n `on a ship'). Moreover, the ending -n is so regular that the Hungarian Wiktionary simply marks this case as "-on/-en/ön" (in English it is called superessive). In contrast to this, in the Czech translation v lodích, the location is expressed by a combination of a separate word (a preposition v `in') and the locative plural ending ích which is added to the stem loď `ship' and cannot be subdivided into a part expressing plural and a part expressing the locative case. Therefore Czech is not an agglutinative language.
