seront

Seront is the third-person plural form of the French verb être in the futur simple (simple future). In English, it corresponds to "they will be." Être is an irregular verb, and ser- is the particular future stem for this form. The standard futur simple endings are -ai, -as, -a, -ons, -ez, -ont, so the complete form is sera + ont, giving seront for the plural.

Etymology and formation: The stem ser- derives from historical forms of the verb être and its Latin origins. While être has many irregularities in its various tenses, seront follows the regular futur simple endings attached to the ser- stem. This pattern is shared with other conjugations in the same tense, though each verb may use a different stem.

Usage: Seront is used to express a definite future state for a plural subject. Examples include: Ils seront présents demain. (They will be present tomorrow.) Les résultats seront publiés la semaine prochaine. (The results will be published next week.) Quand ils seront prêts, nous partirons. (When they are ready, we will leave.) In negative form, it appears as Ils ne seront pas disponibles, and in questions as Seront-ils prêts?

Notes: Seront appears exclusively in contexts requiring the future tense and cannot be used in past or present constructions. It agrees in number with the subject (they). See also: être, conjugation of être, futur simple.
