Je n’achète pas d’abricots aujourd’hui, parce qu’il me reste déjà des pêches à la maison.

In French, the basic negation usually goes around the conjugated verb:

• je n’achète pas
• literally: I do not buy

So French does not normally say something like je ne pas achète. The two negative parts are:

• ne / n’ before the verb
• pas after the verb

In everyday spoken French, people often drop ne, so you may hear j’achète pas, but in standard written French, ne is kept.

The verb is acheter. It is one of the common verbs where the e in the stem changes to è in some present-tense forms.

So you get:

• j’achète
• tu achètes
• il/elle achète
• ils/elles achètent

But:

• nous achetons
• vous achetez

This happens because the syllable after that e is silent in forms like achète.

After pas in a negative sentence, des / du / de la usually change to de / d’ when talking about an indefinite amount or number of things.

Compare:

• J’achète des abricots. = I’m buying some apricots.
• Je n’achète pas d’abricots. = I’m not buying any apricots.

So this is a very important rule:

• affirmative: des abricots
• negative: pas d’abricots

A common exception is with être:

• Ce ne sont pas des abricots.

This is called elision. In French, certain short words drop their final vowel before a following word that begins with a vowel or silent h.

So:

• ne + achète → n’achète
• que + il → qu’il

This helps French sound smoother and more natural.

Because the subject je is followed by ne, not directly by achète.

Compare:

• affirmative: J’achète
• negative: Je n’achète pas

You only get j’ when je comes directly before a vowel sound. Here it does not, because n’ comes in between.

Yes, aujourd’hui is fairly flexible.

In this sentence, aujourd’hui comes near the end of the first clause:

• Je n’achète pas d’abricots aujourd’hui

That is very natural and means today modifies the whole action.

You could also say:

• Aujourd’hui, je n’achète pas d’abricots...

That puts extra emphasis on today.

So the original placement is normal, but not the only possible one.

Parce que means because and introduces the reason:

• ... parce qu’il me reste déjà des pêches...
• ... because I already have some peaches left...

You often can use car instead, but there is a difference in tone:

• parce que = more common and natural in everyday speech
• car = a bit more formal or written

So in normal conversation, parce que is the safest choice.

Il me reste des pêches means I have some peaches left or There are some peaches left for me.

A more literal breakdown is:

• il reste = there remains / there are left
• me = to me / for me
• des pêches = some peaches

The il here does not mean a specific he. It is part of a common French structure used to say that something remains or is left.

So:

• Il me reste des pêches = I still have some peaches left.

French object pronouns usually come before the conjugated verb.

So French says:

• il me reste

not

• il reste me

Here me means to me / for me. French places that little pronoun before the verb as a normal word-order rule.

You will see this a lot:

• il me parle = he speaks to me
• tu me donnes = you give me
• il me reste = I have left / there remains to me

Because the two noun phrases are in different grammatical situations.

Earlier:

• Je n’achète pas d’abricots
• after negation, des becomes de / d’

Later:

• il me reste déjà des pêches
• this is not after pas, so the normal plural article des stays

So:

• negative purchase: pas d’abricots
• positive remaining quantity: des pêches

Déjà usually means already.

Here it suggests that the speaker already has enough fruit at home, so buying apricots today is unnecessary.

So the idea is something like:

• because I already still have some peaches left at home

In natural English, you might not always translate déjà very heavily, but in French it adds the idea that this is an existing situation the speaker is taking into account.

French usually needs an article before a plural count noun when it means some.

So:

• des pêches = some peaches

English often omits the article in places where French cannot:

• English: I still have peaches
• French: Il me reste des pêches

Bare plural nouns are much less common in French than in English.

Yes, chez moi is possible, but the nuance is a little different.

• à la maison = at home
• chez moi = at my place / at my home

In this sentence, à la maison sounds very natural and neutral. It focuses on the location at home.

You could say:

• ... parce qu’il me reste déjà des pêches chez moi.

That is also correct, but it feels slightly more like at my place than simply at home.

French present tense is often used for:

• what is happening now
• what is true now
• what someone is doing today

So here:

• Je n’achète pas... aujourd’hui = I’m not buying... today
• il me reste... = I still have... left

Both are current, present-time ideas, so the present tense is exactly what French normally uses.
