Grammar is the skeleton of a language. Once you understand how it works, you can build sentences, express ideas, and truly communicate. We'll focus on four key areas that form the foundation of French: verb tenses, adjective agreement, articles, and prepositions. Mastering these will give you the confidence to write and speak accurately.

Verbs are the engines of your sentences. In French, they change form, or conjugate, based on who is performing the action (the subject) and when the action happens (the tense). Let's start with the present tense, used for actions happening now or general truths.

Most French verbs fall into one of three regular groups, identified by the last two letters of their infinitive form: -er, -ir, and -re. Each group has its own set of endings in the present tense.

So, for the verb parler (to speak), you would say je parle. For finir (to finish), it's nous finissons. Notice that for -re verbs, the ending for il/elle/on is nothing, you just drop the -re from the infinitive: il vend.

Next, let's look at the past. The most common past tense is the passé composé. It's used for completed actions and translates to the simple past in English (e.g., "I spoke"). It's a compound tense, meaning it has two parts: an auxiliary verb (avoir or être) and a past participle.

For most verbs, the auxiliary is avoir. The past participle for regular verbs is formed by changing the infinitive ending:

• -er becomes -é (parler → parlé)
• -ir becomes -i (finir → fini)
• -re becomes -u (vendre → vendu)

This gives us sentences like J'ai parlé (I spoke), Tu as fini (You finished), and Il a vendu (He sold). A small group of verbs, mostly related to movement, use être as the auxiliary. We'll explore those later.

Finally, the future. The futur simple is used for actions that will happen. It's one of the easiest tenses to form. For regular verbs, you just add the future endings to the infinitive form of the verb.

For example, to say "I will speak," you take the infinitive parler and add -ai to get je parlerai. To say "They will sell," you take vendre and add -ont to get ils vendront. It's that straightforward for most verbs.

In French, nouns have a gender, either masculine or feminine. This is a core concept that affects other words in the sentence, especially adjectives. Adjectives must agree in gender and number (singular or plural) with the noun they describe.

Let's see it in action with the adjective grand (big/tall).

• A big boy (masculine, singular): un grand garçon
• A big girl (feminine, singular): une grande fille
• Big boys (masculine, plural): de grands garçons
• Big girls (feminine, plural): de grandes filles

Notice how grand changes to grande, grands, and grandes to match the noun. Some adjectives have irregular forms, but this pattern covers the majority.

Articles are small but mighty words that introduce a noun. Like adjectives, they must agree with the noun's gender and number.

The definite articles (the) are le (masculine), la (feminine), l' (before a vowel), and les (plural). The indefinite articles (a/an/some) are un (masculine), une (feminine), and des (plural).

• The book / A book: le livre / un livre
• The table / A table: la table / une table
• The friends / Some friends: les amis / des amis

Prepositions are words like à (to, at), de (of, from), dans (in), pour (for), and sur (on). They link words and show relationships. Their usage can sometimes be tricky because they don't always translate directly from English. For instance, when you say you are going to a city, you use à.

Getting comfortable with these foundational rules is the most important first step. Practice them, and you'll be well on your way to building clear and correct French sentences.

Time to check your understanding of these core concepts.

Keep practicing these fundamentals. They are the key to unlocking the rest of the language.
