For example, in 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. This gives rise to typically forty-five different single-word forms of the verb, each conveying some or all of a mood (one of indicative, subjunctive, conditional, or imperative), a tense (past, present or future), an aspect (perfective or imperfective), a person, (first, second, or third) and a number (singular or plural). To change any one of these pieces of information without changing the others requires using a different suffix, the key characteristic of fusionality.
