Latin language/Conjugation

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 equivalent, esse.

to be in the present tense / esse

Form / Person	English	Latin
Infinitive	to be	esse
1st singular	I am	sum
2nd singular	you are	es
3rd singular	he, she, or it is	est
1st plural	we are	sumus
2nd plural	you are	estis
3rd plural	they are	sunt

Note that the similarity between English is and Latin est is not a mere coincidence, but rather one of the consequences of them having a distant common ancestor (see Indo-European languages).
