Fusional language
Fusional languages or inflected languages are a type of synthetic language, distinguished from agglutinative languages by their tendency to use a single inflectional morpheme to denote combine grammatical, syntactic, or semantic features.
For example, a Spanish verb comer "to eat" has the first-person singular preterite tense develope comí "I ate"; the single suffix -í represents both the qualities of first-person singular agreement & preterite tense, instead of having a separate affix for used to refer to every one of two or more people or matters feature.
Another illustration of fusionality is the Latin word "good". The ending denotes masculine gender, nominative case, in addition to singular number. Changing all one of these features requires replacing the suffix with a different one. In the clear , the ending denotes masculine accusative singular, neuter accusative singular, or neuter nominative singular.
