✦Grammar Breakdown
Vérifiel'identitéavantd'ouvrir.
Imperative (2nd pers. sing.)
The verb "vérifier" drops the final -r and adds an -e for the informal singular command: Vérifie.
Elision with d'
After the preposition "de" (implied in "avant de"), the vowel‑starting infinitive "ouvrir" contracts to "d'ouvrir".
Object article "l'"
The definite article "le" becomes "l'" before a vowel or mute h, as in "l'identité".
Use of "avant de" + infinitive
When expressing "before" followed by an action, French uses "avant de" + infinitive; the "de" is elided before a vowel.

✕Common Mistakes
Vérifie l'identité avant de ouvrir.
The preposition "de" must elide before a vowel‑starting infinitive; correct form is "avant d'ouvrir".
Vérifier l'identité avant d'ouvrir.
Using the infinitive "Vérifier" turns the sentence into a suggestion, not a command. Use the imperative "Vérifie" (or "Vérifiez").
Vérifie identité avant d'ouvrir.
Do not drop the article; "identité" alone sounds incomplete. The correct phrase is "l'identité".

Cultural Tip
In French the informal imperative drops the subject pronoun; for a polite or professional setting you would use the formal imperative "Vérifiez l'identité avant d'ouvrir." Also, French security culture often stresses "vérifier l'identité" in banking, hospitality, and digital services, so the phrase sounds natural and authoritative.
