In Italian, almost every verb in its basic, unconjugated form—the infinitive—ends in one of three ways: with -are, -ere, or -ire. Think of these as three big families. Learning to spot which family a verb belongs to is the first step to figuring out how to use it correctly in a sentence.

This ending isn't just a label; it's a guide. It tells you which set of rules to follow when you change the verb to match a subject. This process is called conjugation. For now, we'll focus on just identifying these groups.

The first and most common group of verbs are those ending in -are. You'll encounter these all the time. The core part of the verb, before the -are, is called the stem. For example, in the verb parlare (to speak), the stem is parl-.

When you conjugate an -are verb, you drop the ending and add a new one to the stem. The new ending depends on who is doing the action (I, you, we, etc.).

The second family of verbs ends in -ere. They are less common than -are verbs but still numerous. They follow the same principle: find the stem, drop the -ere, and add the correct ending for the subject.

For vedere (to see), the stem is ved-. This is the part that remains constant as you conjugate it. The endings for -ere verbs are different from those for -are verbs, which is why recognizing the group is so important.

The final group consists of verbs that end in -ire. This group includes many common verbs you'll use daily. Just like the other two families, you'll work with the verb's stem to conjugate it.

So, for dormire (to sleep), you'll use the stem dorm- as your base. The -ire family has its own unique set of endings.

Let's review these concepts before moving on.

Time to check your understanding.

Recognizing these three verb families is a fundamental skill for speaking and writing in Italian.
