Mastering Spanish Present Tense Sentence Translation

Exam Tip: If you are asked to identify these in a worksheet, a common instruction is to underline the conjugated verb and circle the infinitive to demonstrate you understand which one is doing the "work" of matching the subject.

Identifying Infinitives: The -ar, -er, and -ir Endings

How do you know if a verb is an infinitive? In Spanish, all infinitives end in one of three specific ways. If you see these endings, you are looking at a verb that has not been conjugated:

When translating, you will often take a verb like trabajar and leave it exactly as it is, even if the subject is "he," "she," or "we," because it follows a conjugated verb.

Subject-Verb Agreement in Action

The most critical step in translation is ensuring the first verb agrees with the subject. Let's look at how the verb necesitar (to need) changes based on who is speaking:

• Yo (I) $\rightarrow$ necesito
• Ella (She) $\rightarrow$ necesita
• Nosotros (We) $\rightarrow$ necesitamos

Once you have chosen the correct form for the first verb, you simply attach the infinitive.

Worked Examples

Let's apply these rules to common sentence patterns found in language exercises:

Example A: "I need to drink water every morning."

1. Identify the driver: "I need" $\rightarrow$ The subject is Yo, so we conjugate necesitar to necesito.
2. Identify the action: "to drink" $\rightarrow$ The infinitive is beber.
3. Combine: Yo necesito beber agua cada mañana.

Example B: "She promises to share her food."

1. Identify the driver: "She promises" $\rightarrow$ The subject is Ella, so we conjugate prometer to promete.
2. Identify the action: "to share" $\rightarrow$ The infinitive is compartir.
3. Combine: Ella promete compartir su comida.

Example C: "We decide to eat at home."

1. Identify the driver: "We decide" $\rightarrow$ The subject is Nosotros, so we conjugate decidir to decidimos.
2. Identify the action: "to eat" $\rightarrow$ The infinitive is comer.
3. Combine: Nosotros decidimos comer en casa.

Summary Checklist for Translation

When you are faced with a translation task, follow this mental checklist to avoid common errors:

1. Find the subject: Is it I, you, he, she, we, or they?
2. Conjugate the first verb: Change the ending of the first verb to match that subject in the present tense.
3. Find the second verb: Look for the action.
4. Keep the second verb in the infinitive: Ensure it ends in -ar, -er, or -ir and do not change its ending.
5. Check the "To" relationship: Remember that you do not need an extra word for "to"; the infinitive form handles that naturally.

By separating the "intent" (the conjugated verb) from the "action" (the infinitive), you can master complex Spanish sentences with confidence.
