Être (to be) · Futur
By TutorLily Editorial Team · Last updated
Être in the French futur simple is: je serai, tu seras, il/elle/on sera, nous serons, vous serez, ils/elles seront. The futur simple of être uses the irregular stem 'ser-' (NOT 'êtr-'). 'Je serai à Paris demain' = 'I will be in Paris tomorrow'. Same stem powers the conditionnel ('je serais'). The futur is also used for conjecture: '¿il sera fatigué?' = he must be tired.

Working with the futur
The futur simple ("je parlerai") describes future actions, predictions, and conjecture about the present. In conversation it competes with the futur proche ("je vais parler" — going-to future), which is more common for near-term plans. Use the futur simple for distant or formal futures ("un jour, je voyagerai en Asie") and for conjecture ("il sera fatigué" = he must be tired). The futur stem is the full infinitive for regular verbs (parler-, finir-, vendr-), with a small set of irregular stems for high-frequency verbs: être → ser-, avoir → aur-, aller → ir-, faire → fer-, savoir → saur-, pouvoir → pourr-, vouloir → voudr-, venir → viendr-, devoir → devr-, voir → verr-.
