Marie hésite entre un pantalon violet et une jupe marron, parce qu’elle veut rester discrète au travail.

Because hésiter entre X et Y is the normal French pattern for to hesitate between X and Y.

• Marie hésite entre un pantalon violet et une jupe marron = Marie is hesitating between a purple pair of trousers and a brown skirt.

You can think of it as:

• hésiter = to hesitate
• entre = between

So French uses entre ... et ... just like English uses between ... and ....

Because every French noun has a grammatical gender.

• pantalon is masculine → un pantalon
• jupe is feminine → une jupe

The articles must match the gender of the noun:

• un = a / an for masculine singular nouns
• une = a / an for feminine singular nouns

This grammatical gender does not necessarily mean anything about real-world gender. It is just part of the noun.

In French, most adjectives come after the noun, and colors usually do too.

So:

• un pantalon violet = a purple pair of trousers
• une jupe marron = a brown skirt

This is different from English, where adjectives usually come before the noun.

A good basic rule is:

• noun first
• descriptive adjective after

Because violet is describing pantalon, and pantalon is masculine singular.

Adjectives in French usually agree with the noun they describe:

• masculine singular: violet
• feminine singular: violette
• masculine plural: violets
• feminine plural: violettes

So:

• un pantalon violet
• une jupe violette

In your sentence, violet matches the masculine noun pantalon.

Because marron as a color adjective is usually invariable.

That means it does not change for gender or number:

• une jupe marron
• un pantalon marron
• des chaussures marron

This happens with several color words that originally come from nouns, such as:

• orange
• marron
• olive
• crème

So even though jupe is feminine, marron stays marron.

This is called elision.

que becomes qu’ before a word starting with a vowel sound, such as elle.

So:

• que elle ❌
• qu’elle ✅

French does this very often to make pronunciation smoother.

Other common examples:

• je aime → j’aime
• le ami → l’ami
• si il → s’il

Parce que means because.

In this sentence:

• parce qu’elle veut rester discrète au travail = because she wants to stay discreet at work

Again, que becomes qu’ before elle because of elision.

So the full structure is:

• parce que = because
• parce qu’elle = because she

Because discrète is an adjective, not an adverb.

Here, rester works like to remain / to stay, and it links the subject to a description. So French uses an adjective that agrees with the subject:

• elle veut rester discrète = she wants to remain discreet

Since elle is feminine singular, the adjective is discrète.

If you used discrètement, that would mean discreetly, which describes how someone does something, not what they are like.

Compare:

• Elle reste discrète. = She remains discreet.
• Elle parle discrètement. = She speaks discreetly.

Because it agrees with elle / Marie, who is feminine singular.

The basic masculine form is:

• discret

The feminine singular form is:

• discrète

So:

• Il veut rester discret.
• Elle veut rester discrète.

This is a very common pattern in French: adjectives often change form to match the noun or pronoun they describe.

Au travail means at work or in the workplace.

It is made from:

• à = at / to
• le travail = work

And à + le contracts to au:

• à le ❌
• au ✅

So:

• au travail = at work

This is a very common contraction in French:

• à + le → au
• à + les → aux

French often uses the present tense to describe what someone is doing, feeling, or thinking right now.

• Marie hésite = Marie is hesitating / Marie hesitates
• elle veut = she wants

In English, you might naturally say is hesitating, but French often just uses the simple present where English prefers the present continuous.

So Marie hésite can sound like:

• Marie is hesitating
• Marie hesitates

The exact English choice depends on context.

Yes. In French, un pantalon is singular and refers to one pair of trousers/pants.

So French treats it as one item:

• un pantalon

English is different because pants or trousers are grammatically plural, even when referring to one item.

That is why:

• un pantalon violet = a purple pair of trousers / purple pants

Yes, often you could, but the tone changes a little.

• parce que is the most common everyday way to say because
• car also means for / because, but it often sounds a bit more formal or written

So:

• Marie hésite..., parce qu’elle veut rester discrète au travail. sounds natural and everyday.

• Marie hésite..., car elle veut rester discrète au travail. is also correct, but slightly more formal.

For normal spoken French, parce que is usually the safer choice.
