What is an infinitive?

​A Spanish infinitive is the basic, unchanged form of a verb.

Let's Recap!

Before we begin to dive in learning -AR verbs and conjugations, we must first review Subject Pronouns.

Multiple Choice

What is a subject pronoun?

• A word that connects two ideas or phrases together (like and, but, or).

• A word that shows the action or state of being in a sentence (like run, talk, is).

• A word that describes a noun by giving more detail (like big, small, happy).

• A word that replaces a noun and shows who is doing the action in a sentence (like yo, tú, él).

Conjugating -AR verbs

Step-By-Step

1. Identify the verb type → -AR. (Ex. hablar)

2. Drop the -ar → get the stem. (Ex. habl-)

3. Add the ending that matches the subject: yo hablo (I speak)

Multiple Select

Directions: Circle every -AR infinitive. Underline any that are NOT -AR.

• hablar

• comer

• estudiar

• vivir

• bailar

Dropping the verb ending tells us WHO is doing the action.

Multiple Choice

True / False – To conjugate an -AR verb, you keep the ending -ar and just add the subject pronoun in front.

• TRUE

• FALSE

We Do

1. Tú (estudiar) mucho. → estudias

2. Nosotros (necesitar) agua. → necesitamos

3. Ella (escuchar) música. → escucha

Multiple Choice

True / False – The correct ending for yo with -AR verbs is -o (ex: hablo = “I talk”).

• TRUE

• FALSE

Multiple Choice

True / False – In the present tense, nosotros endings for -AR verbs are always -amos (ex: hablamos = “we talk”).

• TRUE

• FALSE

Multiple Choice

True / False – The verb form hablan means “they talk” or “you all talk.”

• TRUE

• FALSE

Common Pitfalls

• Leaving the infinitive: yo hablar ❌ instead of yo hablo ✅

• Mixing endings: yo hablas ❌ (yo needs -o)

• Forgetting nosotros = -amos

• Assuming English -s means Spanish -s: “he talks” ≠ él hablas (should be él habla)
