Je vérifie l’adresse de livraison avant la livraison.

Because adresse starts with a vowel sound, French uses l’ instead of la. This is called elision.

• la + adresse → l’adresse
• You see the same thing in:
  • l’école
  • l’amie
  • l’homme

So l’adresse still means the address, and adresse is still a feminine noun.

In l’adresse de livraison, the phrase de livraison works like for delivery or delivery-related. It is a noun complement, and in this kind of expression French often uses de + noun without an article.

So:

• une adresse de livraison = a delivery address
• une date de naissance = a birth date
• une salle de bain = a bathroom

If you said de la livraison, it would sound more like of the delivery or about the delivery, which is a different idea.

Because these two parts of the sentence are doing different jobs.

• de livraison is part of the noun phrase l’adresse de livraison. It describes what kind of address it is: a delivery address.
• avant la livraison is a normal prepositional phrase meaning before the delivery. Here, livraison is a specific event or process, so French uses the definite article la.

Compare:

• une adresse de livraison = a delivery address
• avant la livraison = before the delivery

So the difference comes from structure, not from the word livraison itself.

Vérifie is the present tense of vérifier, with je.

Full present-tense forms:

• je vérifie
• tu vérifies
• il / elle / on vérifie
• nous vérifions
• vous vérifiez
• ils / elles vérifient

In French, the present tense can mean different things depending on context, such as:

• I check
• I am checking
• I do check

Yes. French often uses the simple present where English chooses between I check and I am checking.

So Je vérifie l’adresse de livraison avant la livraison could mean:

• I check the delivery address before delivery (habitual or general)
• I’m checking the delivery address before delivery (right now, depending on context)

If French wants to strongly emphasize that something is happening right now, it can use expressions like être en train de, but that is not necessary here.

This is standard French word order:

• Je = subject
• vérifie = verb
• l’adresse de livraison = direct object
• avant la livraison = time expression

So the pattern is basically:

subject + verb + object + time phrase

That is very common in French and matches normal English word order quite closely in this sentence.

The accent in vérifie is the acute accent: é.

It affects pronunciation and helps show the correct form of the word.

• vérifier is pronounced with é
• verifier without the accent is not the correct standard spelling in French

The é usually sounds something like ay in English, though not exactly the same.

So the accent is not optional; it is part of the correct spelling.

Yes, it is natural. French often repeats a noun if that makes the meaning clear.

Here:

• l’adresse de livraison = the delivery address
• avant la livraison = before delivery / before the delivery

Even though livraison appears twice, each phrase has a different role. Native speakers would not necessarily find this strange.

That said, depending on context, someone might rephrase it to avoid repetition, but the original sentence is completely normal and clear.

Yes, it is a very common expression, especially in shopping, shipping, and online forms.

Common related expressions include:

• adresse de livraison = delivery address
• adresse de facturation = billing address
• frais de livraison = delivery charges
• délai de livraison = delivery time

So this is a useful pattern to learn: noun + de + noun

Sometimes pour la livraison is possible, but it does not mean exactly the same thing.

• l’adresse de livraison is the standard term for delivery address
• une adresse pour la livraison would sound more like an address for the delivery, which is understandable but less idiomatic in many contexts

So if you mean the usual label on a form or in shipping, adresse de livraison is the best choice.

Usually, the final e in je and the final e in vérifie are not strongly pronounced.

Very roughly:

• Je often sounds like zhuh or even becomes very light in fast speech
• vérifie ends more like vee-ray-fee, without a strong extra sound after the last i

So you should not pronounce them like full English vowels at the end.

A rough pronunciation of the whole sentence is:

zhuh vay-ree-fee la-dress duh lee-vray-zohn ah-vahn la lee-vray-zohn

That is only approximate, but it may help at a beginner stage.

Because French does not always use possessive words like my when the meaning is already clear from context.

The sentence simply says the delivery address, not my delivery address.

Depending on context, that could refer to:

• the customer’s address
• an order’s delivery address
• a specific address already being discussed

If you wanted to say my delivery address, you could say:

Je vérifie mon adresse de livraison avant la livraison.

So the original sentence is not missing anything; it is just more neutral.
