keel, milles sõna morfoloogiliste koostisosade vahelised piirid ei ole selgesti eristatavad
a type of synthetic language, distinguished from agglutinative languages by its tendency to overlay many morphemes to denote grammatical, syntactic or semantic change
in this kind of language words display grammatical relationship morphologically: they typically contain more than one morpheme, but unlike agglutinative languages there is no one-to-one correspondence between these morphemes and the linear sequence of morphs

Examples of fusional Indo-European languages are: Sanskrit (and the modern Indo-Aryan languages), Greek (classical and modern), Latin, Lithuanian, Russian, German, Icelandic, Polish, Croatian, Serbian, Slovak, Ukrainian, and Czech. ... An illustration of fusionality is the Latin word bonus („good“). The ending -us denotes masculine gender, nominative case, and singular number. Changing any one of these features requires replacing the suffix -us with a different one. In the form bonum, the ending -um denotes either masculine accusative singular, neuter accusative singular, or neuter nominative singular.
Fusional languages may have a large number of morphemes in each word, but morpheme boundaries are difficult to identify because the morphemes are fused together.
