Nous parlons souvent français à l’université.

Because the subject is nous (we), and the verb parler has to agree with that subject.

Present tense of parler:

• je parle
• tu parles
• il / elle / on parle
• nous parlons
• vous parlez
• ils / elles parlent

So Nous parlons means we speak or we are speaking.

In regular -er verbs, the nous form in the present tense usually ends in -ons.

For example:

• nous parlons = we speak
• nous aimons = we like
• nous travaillons = we work

So -ons is the normal ending for nous with most regular -er verbs.

In French, adverbs of frequency such as souvent (often) are commonly placed after the conjugated verb.

So:

• Nous parlons souvent français.

This is the natural French word order.

English often says:

• We often speak French.

French usually prefers:

• We speak often French in literal order, even though that sounds unnatural in English.

After verbs like parler, French usually does not use an article before the name of a language.

So you say:

• parler français
• parler anglais
• parler espagnol

Not:

• parler le français in this normal sense

However, le français can be used when the language itself is the subject or object in a more general sense:

• Le français est difficile. = French is difficult.
• J’aime le français. = I like French.

But after parler, the article is usually omitted.

In French, names of languages are normally not capitalized.

So:

• français
• anglais
• allemand

This is different from English, where we write French, English, and German with capital letters.

A useful contrast:

• un Français = a Frenchman / French person
• français = French language / French adjective

So capitalization can change the meaning.

À l’université means at the university or in university / at university, depending on context.

It is à + l’ because université is a singular noun beginning with a vowel sound, so French uses l’ instead of le or la.

Compare:

• à l’université
• à l’école
• à l’hôpital

The full structure is:

• à = at / in / to
• l’ = the

So à l’université literally means at the university.

French often uses à with places like schools, universities, work, and cities when talking about being there or doing something there.

So:

• à l’université = at university / at the university
• à l’école = at school
• au travail = at work

Dans l’université would suggest something more physical, like inside the university building or grounds, and is less natural in a general sentence like this.

So if you mean the usual idea of studying or being at university, à l’université is the normal choice.

It can mean either, depending on context.

French present tense often covers both:

• we speak
• we are speaking

So Nous parlons souvent français à l’université can mean:

• We often speak French at university or
• We are often speaking French at university

In practice, the first translation is usually the most natural in English.

Parlons is pronounced roughly like par-lon.

A few helpful points:

• the s at the end is normally silent
• the on is a nasal sound in French, not a full English on
• the r is the French r, produced farther back in the throat than in English

So it is not pronounced like parlonss.

Français is pronounced roughly like frahn-say.

Helpful points:

• the ç makes an s sound
• the final -ais sounds like ay
• the an is a nasal vowel, so it is not pronounced exactly like English an

So the word sounds close to frahn-say, not fran-kays or fran-sess.

The apostrophe shows elision.

French drops the vowel of le or la before a word that begins with a vowel or mute h:

• le + université would be awkward
• so it becomes l’université

Other examples:

• l’école
• l’hôtel
• l’ami

This is very common in French spelling and pronunciation.

Yes. In everyday spoken French, people often use on instead of nous.

So a very common spoken version would be:

• On parle souvent français à l’université.

This still means we often speak French at university.

The difference is mainly register:

• nous is a bit more formal or careful
• on is very common in everyday speech

Both are correct.

This is the normal and natural order:

• Nous = subject
• parlons = verb
• souvent = adverb
• français = object / complement after parler
• à l’université = place

So the sentence follows a very typical French pattern: subject + verb + adverb + language + place

You could move some parts for emphasis in special contexts, but the given order is the most straightforward and standard one.
