Grammatical conjugation
Grammatical conjugation is the creation of derived forms of a verb from one basic form. Conjugation may be affected by person, number, gender, tense, mood, voice, or some other language-specific factor or factors. When a verb is used to function as the action done by a subject, the verb must be conjugated in most languages.
For example, here's a sample conjugation of the English verb to be and its Latin and French equivalents, esse and être.
