Je dépose mon chemisier au pressing avant la réunion.

Because je takes the -e ending in the present tense for regular -er verbs.

The verb is déposer = to drop off / to leave / to place.

Present tense:

• je dépose
• tu déposes
• il / elle dépose
• nous déposons
• vous déposez
• ils / elles déposent

So with je, the correct form is dépose.

Here, déposer means to drop off something somewhere, especially to leave it for a service.

So in this sentence, Je dépose mon chemisier au pressing means the speaker is taking the blouse to the dry cleaner and leaving it there.

Depending on context, déposer can also mean:

• to put down
• to place
• to deposit
• to file (for example, a complaint or application)

But in this sentence, drop off is the most natural meaning.

Un chemisier means a blouse, usually a woman’s blouse or dress shirt.

It is a masculine noun, which can surprise English speakers because it refers to an item of women’s clothing. In French, grammatical gender does not always match real-world gender.

So:

• un chemisier = a blouse
• mon chemisier = my blouse

Because chemisier is grammatically masculine: un chemisier.

French possessive adjectives agree with the noun possessed, not with the owner.

So:

• mon chemisier = my blouse
• ton chemisier = your blouse
• son chemisier = his/her blouse

Even if the speaker is a woman, it is still mon chemisier, because the noun chemisier is masculine.

Au pressing means to the dry cleaner’s or at the dry cleaner’s.

Pressing is a French noun borrowed from English, but in French it usually refers to a dry-cleaning shop. So although it looks familiar, it does not mean exactly the same thing as English pressing.

In everyday French:

• aller au pressing = to go to the dry cleaner’s
• déposer quelque chose au pressing = to drop something off at the dry cleaner’s

Because à + le contracts to au in French.

So:

• à + le = au
• à + les = aux

Since pressing is masculine singular (le pressing), you get:

• au pressing

Examples:

• Je vais au pressing.
• Il est au bureau.
• Nous parlons aux voisins.

Because au pressing expresses going to or being at that place as a destination or service location.

French often uses à / au / à la / aux with shops, businesses, and public places:

• au pressing
• à la boulangerie
• au bureau
• à la banque

Dans means in / inside and focuses more on physical location inside something.

So:

• Je dépose mon chemisier au pressing = I drop off my blouse at the dry cleaner’s
• Je suis dans le pressing = I am inside the dry-cleaning shop

Both can be possible in different contexts, but au pressing is the natural choice here.

French normally uses an article where English sometimes does not.

Here, avant la réunion literally means before the meeting. French needs the definite article la with réunion.

So even if English might sometimes say:

• before meeting
• before the meeting

French naturally says:

• avant la réunion

Because réunion is a feminine noun:

• la réunion = the meeting

Because avant is followed directly by a noun phrase when you mean before + noun.

So:

• avant la réunion = before the meeting
• avant le dîner = before dinner
• avant le départ = before the departure

You use avant de before an infinitive verb, not before a noun:

• avant de partir = before leaving
• avant de manger = before eating

So:

• avant la réunion ✅
• avant de la réunion ❌

Yes. Je dépose is in the present tense.

In French, the present tense can describe:

• something happening now
• a habit
• a planned or near-future action, depending on context

So this sentence could mean:

• I’m dropping off my blouse at the dry cleaner’s before the meeting
• I drop off my blouse at the dry cleaner’s before the meeting
• possibly I’m going to drop off my blouse... if the context makes that clear

French often uses the simple present where English might prefer am doing or am going to do.

Sometimes, but the meaning changes slightly.

• déposer = drop off / leave somewhere
• laisser = leave
• amener = bring

In this context, déposer is the most natural because it emphasizes taking the blouse to the dry cleaner and leaving it there for service.

Compare:

• Je dépose mon chemisier au pressing. = I drop off my blouse at the dry cleaner’s.
• Je laisse mon chemisier au pressing. = I leave my blouse at the dry cleaner’s.
  This can work, but it is a little less specific.
• J’amène mon chemisier au pressing. = I bring my blouse to the dry cleaner’s.
  This focuses more on the act of bringing than on leaving it there.

Une réunion usually means a meeting, often in a work, school, or organizational context.

It can be:

• a business meeting
• a staff meeting
• a committee meeting
• a general organized gathering

It often sounds more formal or structured than casual social words like:

• un rendez-vous = an appointment
• une rencontre = a meeting/encounter
• une soirée = an evening party or gathering

So avant la réunion strongly suggests some kind of scheduled meeting.

A careful pronunciation would be roughly:

Je dépose mon chemisier au pressing avant la réunion.
zhuh day-POHZ mohn shuh-mee-ZYAY oh PRESS-ing ah-VAHN lah ray-oo-NYON

A few helpful points:

• Je sounds like zhuh
• dépose has a z sound in the middle: day-pohz
• mon has a nasal vowel; the n is not fully pronounced like English n
• chemisier ends with a sound like -zyay
• avant has a nasal ending
• réunion has three clear parts: ré-u-nion

In natural speech, French rhythm matters a lot, so it will flow together smoothly.

In standard everyday French, au pressing is very common and natural for to the dry cleaner’s.

Other expressions exist, but they are less common or used differently:

• le nettoyage à sec = dry cleaning, as a process
• le pressing = the dry-cleaning shop/service

So:

• Je vais au pressing. ✅ very natural
• Je fais nettoyer mon chemisier à sec. ✅ I’m having my blouse dry-cleaned
• au nettoyage à sec is possible in some contexts, but less idiomatic as the everyday destination phrase

For a learner, au pressing is the best phrase to remember here.
