Connaître (to know) · Futur

By TutorLily Editorial Team · Last updated

Connaître in the French futur simple is: je connaîtrai, tu connaîtras, il/elle/on connaîtra, nous connaîtrons, vous connaîtrez, ils/elles connaîtront. The futur simple of connaître uses the stem 'connaîtr-' (drop -e from infinitive — keeps the circumflex traditionally). 'Je connaîtrai mieux la ville' = 'I'll know the city better'. The 2016 reform also accepts 'connaitr-' without circumflex.

Tip

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-.

Questions

Frequently asked questions

How do you conjugate connaître in the futur?
The futur of connaître uses 'connaîtr-' (drop -e from infinitive): je connaîtrai, tu connaîtras, il/elle/on connaîtra, nous connaîtrons, vous connaîtrez, ils/elles connaîtront. The circumflex is traditional but optional after 2016 reform.
Should I write 'connaîtrai' or 'connaitrai'?
Both are now accepted. The traditional spelling 'connaîtrai' (with circumflex) remains the standard in most formal writing and most French dictionaries. The 1990 spelling reform (made official in 2016) accepts 'connaitrai' without circumflex. Choose one and stay consistent — but 'connaîtrai' is the safer default for SEO and formal contexts.
When do I use 'je connaîtrai' instead of 'je vais connaître'?
Both express future knowing/meeting. 'Je connaîtrai' (futur simple) feels slightly more formal. 'Je vais connaître' (futur proche) is more conversational for near-term plans.
