What is the meaning of that goes before certain words in French language and it only used on a specific type word?

You're likely referring to prepositions in French. They are words that precede nouns or pronouns, showing their relationship to other words in a sentence.

Here's a breakdown:

* Prepositions are not limited to a specific type of word. They are used to connect words in a sentence and express relationships like location, time, direction, purpose, and possession.

* Common French prepositions include: à (to/at), de (of/from), en (in/on), sur (on/upon), par (by/through), pour (for), avec (with), sans (without), etc.

For example:

* À la librairie (at the bookstore)

* De Paris (from Paris)

* En France (in France)

* Sur la table (on the table)

* Par la fenêtre (through the window)

* Pour moi (for me)

* Avec des amis (with friends)

* Sans argent (without money)

Key Points:

* Prepositions often change depending on the noun they precede. For example, "à" becomes "au" before a masculine singular noun beginning with a vowel sound.

* Certain prepositions are specific to certain verbs. For example, "penser à" (to think about), "attendre à" (to wait for).
