===Conjugation===
{{main article|Grammatical conjugation}}
[[Grammatical conjugation|Conjugation]] is the alteration of the form of a [[verb]] to encode information about some or all of [[grammatical mood]], [[grammatical voice|voice]], [[grammatical tense|tense]], [[grammatical aspect|aspect]], [[grammatical person|person]], [[grammatical gender]] and [[grammatical number|number]]. In a fusional language, two or more of those pieces of information may be conveyed in a single morpheme, typically a suffix.

For example, in [[French language|French]], the verbal suffix depends on the mood, tense and aspect of the verb, as well as on the person and number (but not the gender) of its subject. That gives rise to typically [[French conjugation#First-group verbs (-er verbs)|45 different single-word forms]] of the verb, each of which conveys some or all of the following:
*'''mood''' ([[indicative mood|indicative]], [[subjunctive mood|subjunctive]], [[conditional mood|conditional]] or [[imperative mood|imperative]])
*'''tense''' ([[past tense|past]], [[present tense|present]] or [[future tense|future]])
*'''aspect''' ([[perfective aspect|perfective]] or [[imperfective aspect|imperfective]])
*'''person''' (first, second or third), and
*'''number''' (singular or plural). 

Changing any one of those pieces of information without changing the others requires the use of a different suffix, the key characteristic of fusionality.

English has two examples of conjugational fusion. The verbal suffix ''-s'' indicates a combination of present tense with both third-person and singularity of the associated subject, and the verbal suffix ''-ed'' used in a verb with no auxiliary verb conveys both [[progressive aspect|non-progressive aspect]] and past tense.
