Fusional languages or inflected languages are a type of synthetic language, distinguished from agglutinative languages by their tendency to use single inflectional morphemes to denote multiple grammatical, syntactic, or semantic features.
For example, the Spanish verb comer ("to eat") has the active first-person singular indicative preterite tense form comí ("I ate") where just one suffix, -í, denotes the intersection of the active voice, the first person, the singular number, the indicative mood, and preterite (which is the combination of the past tense and perfective aspect), instead of having a separate affix for each feature.
