Fusional languages or inflected languages are a type of synthetic languages, distinguished from agglutinative languages by their tendency to use a single morpheme in combination with affixes to denote multiple grammatical, syntactic, or semantic changes. For example, the Spanish language verb comer ("to eat") can be expressed in first-person past preterite tense as comí, a word formed removing the "-er" suffix of the verb and replacing it by "-í", that indicate such specific meaning.
