Think of prepositions as the essential glue that holds sentences together. Without them, words would just be a jumbled list. They are small words that connect nouns, pronouns, or verbs to other parts of a sentence, showing the relationship between them. They tell us about location, direction, time, and how things are related.

In a French sentence, a preposition almost always comes directly before the noun, pronoun, or infinitive verb it's connected to. For example, in the phrase un café sans sucre (a coffee without sugar), the preposition sans (without) comes right before sucre (sugar).

Here's some good news for French learners. Unlike nouns, articles, and adjectives that have to agree in gender and number, prepositions are invariable. This means they never change their form. Whether you're talking about one book or many books, a masculine subject or a feminine one, the preposition stays exactly the same.

This simplicity makes them reliable building blocks as you start forming more complex sentences. You learn them once, and they're ready to use in any context without needing to worry about agreement.

While there are many prepositions in French, a few of them do most of the heavy lifting. Getting comfortable with these will take you a long way. Here are four of the most common ones:

When a preposition is paired with a noun or pronoun, it forms a prepositional phrase. For instance, in the example Je vais à Paris, the phrase à Paris acts as a single unit that tells us where I am going. Understanding how to spot these phrases helps in breaking down and understanding French sentence structure.
