Identify the person before choosing an ending
An infinitive names an action without assigning it to a particular person. The dictionary forms hablar, comer, and vivir mean to speak, to eat, and to live. A complete present statement normally needs a finite form, such as hablo, which identifies the speaker. Begin by finding who performs the action, even when that person is understood from context. English word order alone is not a reliable guide to Spanish agreement. A name such as Ana normally takes the same verb form as ella, while a group containing the speaker uses the we form. In a sentence with two names joined together, identify the combined subject before selecting the ending. Keep this decision separate from the verb’s meaning: speaking, eating, and living all require a person choice, even though their endings belong to different classes.
Yo hablo español en clase.
I speak Spanish in class.
The speaker is the subject. Hablo is the present form for yo, so the sentence describes the speaker’s language use rather than merely naming the activity.
Ana come aquí los viernes.
Ana eats here on Fridays.
A single named person takes the third person singular form come. The Friday phrase establishes a routine, so the present is suitable even when Ana is elsewhere now.
Build regular verbs ending in ar
For a regular verb ending in ar, remove those final two letters and add the present ending. With hablar, the useful sequence is hablo, hablas, habla, hablamos, habláis, hablan. The forms correspond to the speaker, a familiar singular listener with tú, a third person or usted, a group containing the speaker, vosotros, and a plural third person or ustedes. These are grammatical categories, not separate words for male and female speakers. A woman and a man both say hablo about themselves. The accent in habláis belongs to the written form and helps show the stressed syllable. Learn the pattern through a small contrast: first describe what you do, then describe what two other people do. The change should come from the subject, not from whether the action happens indoors or outdoors.
Nosotros trabajamos en una biblioteca.
We work in a library.
The subject includes the speaker and at least one other person. The regular ar verb therefore takes amos, giving trabajamos regardless of the workplace.
Mis amigas estudian español.
My friends study Spanish.
The plural noun phrase means they. Keep the stem of estudiar and choose an, producing estudian. The friends’ gender does not change this verb ending.
Follow a complete example
Build a sentence with this meaning: We work in a library. Before looking at the answer, identify which information controls the grammatical choice.
- First, identify the message: We work in a library. Keep that message fixed while comparing forms. A sentence can be grammatical yet communicate something different, so meaning is part of the decision.
- The subject includes the speaker and at least one other person. The regular ar verb therefore takes amos, giving trabajamos regardless of the workplace.
- Now read the complete sentence, Nosotros trabajamos en una biblioteca. Check the words surrounding your choice as well as the choice itself. Explain what would change if the speaker, number, or intended message changed. Then cover this example and reconstruct the sentence from the English cue.
Nosotros trabajamos en una biblioteca. We work in a library.

Compare the er and ir classes
Regular verbs ending in er and ir share several present endings, but their we and vosotros forms differ. Compare como, comes, come, comemos, coméis, comen with vivo, vives, vive, vivimos, vivís, viven. The singular forms and the they forms look alike in their endings; the class difference becomes visible in comemos versus vivimos. Do not invent a separate ending for every new verb. First identify the class, then reuse the matching pattern. A dictionary is useful because spelling alone does not tell you whether a verb is regular in every tense. This lesson practices the regular present, not a promise about all forms of every verb ending in those letters. When you compare two sentences, hold the subject constant so that you can hear and see what the verb class changes.
Nosotras comemos a las dos.
We eat at two.
Comer belongs to the regular er class. With a group that includes the speaker, the present ending is emos, so the complete form is comemos.
Ellos viven cerca del parque.
They live near the park.
Vivir belongs to the ir class, but its present plural ending for they is en. The location phrase supplies information without changing the subject’s number.

Keep subject omission and address separate
Spanish often leaves out a subject pronoun when the verb and the conversation make the reference clear. Trabajo aquí can therefore be a complete statement meaning I work here. Adding yo may clarify a contrast or identify the speaker; it is not automatically an error or automatically required. The shared form habla can refer to he, she, or singular usted, so context may make an explicit subject useful. The address choice also varies by community and relationship. Across Spanish America, ustedes normally serves plural audiences of different familiarity levels. Much of Spain also uses familiar plural vosotros. Familiar singular vos has its own regional patterns, which this lesson does not drill. When a prompt names tú, answer within that pattern; do not treat a form used with vos elsewhere as a universal mistake.
¿Usted vive en este edificio?
Do you live in this building, using usted?
Usted addresses a listener but takes third person singular grammar. The correct finite form is therefore vive, even though English uses the word you in translation.
¿Ustedes hablan inglés?
Do you all speak English, using ustedes?
Ustedes takes the same plural verb form as ellos and ellas. This agreement remains the same whether the conversation feels familiar or more distant.
Recognize common changes inside the stem
Some frequent present verbs change a vowel in their stressed stem. Compare quiero and queremos, or puedo and podemos. The first pair comes from querer, and the second from poder. In these patterns the change occurs in the singular forms and the third person plural, while the nosotros and vosotros forms keep the corresponding infinitive stem vowel. This is a pattern to learn with particular verbs, not an instruction to change every written vowel you encounter. The following infinitive also matters: in quiero comer, only the first verb is finite, while the second names the desired action. Think of a short message you actually need, such as wanting water or being able to help. Learn its full verb group, then change the subject while keeping the rest of the message stable.
Yo quiero aprender español.
I want to learn Spanish.
The present speaker form of querer is quiero. The next verb stays aprender because it names the action wanted by the same subject.
Nosotros podemos ayudar.
We can help.
The we form keeps the stem vowel of poder and adds emos. The following infinitive ayudar stays unchanged because podemos already marks the subject.
Learn useful irregular speaker forms
Several everyday verbs have a special present form for the speaker. Tengo means I have, and hago means I do or I make. These forms are useful in complete messages about possessions, time, and activities. Learn them alongside another person form, such as tiene or hace, so that the special speaker ending does not spread into the entire paradigm by accident. Tener also has a stem vowel change in several forms, while hacer does not follow exactly the same pattern. Calling both verbs irregular identifies a learning task; it does not mean they share every ending. A practical notebook can record the infinitive, one complete sentence about you, and one about another person. Keep the meaning and subject visible, because a bare list of unusual words gives you less help when you need to build an actual message.
Yo tengo dos hermanas.
I have two sisters.
Tengo is the present speaker form of tener. The two sisters are what the speaker has; their plural number does not control the main verb’s agreement.
Mi hermano hace la cena.
My brother makes dinner.
The subject is a single third person, so hacer becomes hace. The irregular speaker form hago is useful to know but does not belong with this subject.
Try the reasoning with less help
Build a sentence with this meaning: I have two sisters. Before looking at the answer, identify which information controls the grammatical choice.
- First, identify the message: I have two sisters. Keep that message fixed while comparing forms. A sentence can be grammatical yet communicate something different, so meaning is part of the decision.
- Tengo is the present speaker form of tener. The two sisters are what the speaker has; their plural number does not control the main verb’s agreement.
- Now read the complete sentence, Yo tengo dos hermanas. Check the words surrounding your choice as well as the choice itself. Explain what would change if the speaker, number, or intended message changed. Then cover this example and reconstruct the sentence from the English cue.

Make negatives and questions without importing do
Place no before the finite verb to negate an ordinary statement: No vivo aquí. Spanish does not add a helper equivalent to English do merely to create a present question or negative. A spoken question uses an appropriate questioning melody, and written Spanish marks its boundaries with ¿ and ? Word order can vary, so do not assume that moving the subject is the only signal of a question. The present can describe a habitual activity or a current situation; in suitable context it can also refer to a planned future event. This lesson concentrates on routines and present situations so that you can first stabilize the person endings. To check your sentence, identify the subject, confirm the verb form, place any negation, and then decide whether you are stating information or asking the listener to supply it.
Yo no trabajo los domingos.
I do not work on Sundays.
No precedes the finite speaker form trabajo. Spanish keeps the ordinary present ending instead of adding an English style helper to the negative statement.
¿Tú comes aquí normalmente?
Do you normally eat here, using tú?
The question uses the ordinary present form comes for tú. Punctuation and questioning intonation distinguish the question without an extra verb meaning do.

Notice the difference
Common mistakes
An infinitive is not the finite statement
Instead ofYo vivir aquí.
For this meaningYo vivo aquí.
The dictionary form names the activity. This ordinary statement requires a finite present form that identifies the speaker. Remove ir and add o for the regular speaker form; then keep the location phrase.
The subject controls the verb
Instead ofYo tienen dos libros.
For this meaningYo tengo dos libros.
The books are plural, but they are not the subject. The subject is yo, so use the speaker form tengo. Look for who has the objects before deciding which noun’s number matters.
A negative still needs agreement
Instead ofElla no estudiar aquí.
For this meaningElla no estudia aquí.
Adding no does not turn the verb into an infinitive. The subject remains one third person, and the finite present form is estudia. The same ending would appear in the corresponding affirmative statement.
From understanding to using
Make your own example.
Try these without answer choices. Say your answer aloud or write it below, then compare your reasoning with the model.
Your turn 1
Introduce your present routine: say that you live in Lima and work in a school.
Compare with a model
Vivo en Lima y trabajo en una escuela.
I live in Lima and work in a school.
Both actions have the speaker as their subject, so each finite verb takes its speaker form. The location does not require a different verb tense. An explicit yo is possible, especially for contrast, but the two endings already identify the subject clearly. Keep the article before the school because the sentence introduces one school without identifying it to the listener.
- Did you preserve the requested meaning?
- Does the form match the person or noun in your message?
- Can you explain your choice before looking at the model?
Your turn 2
Ask one person addressed with usted whether they eat here, then say that you do not eat here.
Compare with a model
¿Usted come aquí? No como aquí.
Do you eat here? I do not eat here.
The question uses third person singular grammar with usted. The reply changes viewpoint to the speaker, so it uses como. Put no before that finite verb. Do not preserve the question’s ending mechanically, because the person answering is now speaking about a different grammatical subject.
- Did you preserve the requested meaning?
- Does the form match the person or noun in your message?
- Can you explain your choice before looking at the model?

Question 1
Complete the sentence for this meaning: I speak Spanish in class.
Yo ___ español en clase.
- hablo
- hablar
Check the answer
Answer: hablo
hablo: The speaker is the subject. Hablo is the present form for yo, so the sentence describes the speaker’s language use rather than merely naming the activity.
hablar: Hablar is the infinitive. It names the activity but does not supply the finite present form required by this statement.
Question 2
Complete the sentence for this meaning: Ana eats here on Fridays.
Ana ___ aquí los viernes.
- comen
- come
Check the answer
Answer: come
comen: Comen agrees with a plural subject. Ana is one person, so that ending does not match this sentence.
come: A single named person takes the third person singular form come. The Friday phrase establishes a routine, so the present is suitable even when Ana is elsewhere now.
Question 3
Complete the sentence for this meaning: We work in a library.
Nosotros ___ en una biblioteca.
- trabajamos
- trabajan
Check the answer
Answer: trabajamos
trabajamos: The subject includes the speaker and at least one other person. The regular ar verb therefore takes amos, giving trabajamos regardless of the workplace.
trabajan: Trabajan is the form for they or plural ustedes. It leaves the speaker outside the grammatical subject.
Question 4
Complete the sentence for this meaning: My friends study Spanish.
Mis amigas ___ español.
- estudia
- estudian
Check the answer
Answer: estudian
estudia: Estudia is singular. It would fit one friend, but the subject here identifies several friends.
estudian: The plural noun phrase means they. Keep the stem of estudiar and choose an, producing estudian. The friends’ gender does not change this verb ending.
Question 5
Complete the sentence for this meaning: We eat at two.
Nosotras ___ a las dos.
- comemos
- comimos
Check the answer
Answer: comemos
comemos: Comer belongs to the regular er class. With a group that includes the speaker, the present ending is emos, so the complete form is comemos.
comimos: Comimos is a past form. It does not express the ordinary present routine requested here.
Question 6
Complete the sentence for this meaning: They live near the park.
Ellos ___ cerca del parque.
- vivimos
- viven
Check the answer
Answer: viven
vivimos: Vivimos includes the speaker. This subject is ellos, so the sentence requires the they form instead.
viven: Vivir belongs to the ir class, but its present plural ending for they is en. The location phrase supplies information without changing the subject’s number.
Question 7
Complete the sentence for this meaning: Do you live in this building, using usted?
¿Usted ___ en este edificio?
- vive
- vives
Check the answer
Answer: vive
vive: Usted addresses a listener but takes third person singular grammar. The correct finite form is therefore vive, even though English uses the word you in translation.
vives: Vives matches tú. The prompt explicitly requests the usted pattern, so its ending must stay consistent with that address.
Question 8
Complete the sentence for this meaning: Do you all speak English, using ustedes?
¿Ustedes ___ inglés?
- hablamos
- hablan
Check the answer
Answer: hablan
hablamos: Hablamos means we speak. The question addresses the listeners as a group and does not include the speaker as its subject.
hablan: Ustedes takes the same plural verb form as ellos and ellas. This agreement remains the same whether the conversation feels familiar or more distant.
Question 9
Complete the sentence for this meaning: I want to learn Spanish.
Yo ___ aprender español.
- quiero
- quero
Check the answer
Answer: quiero
quiero: The present speaker form of querer is quiero. The next verb stays aprender because it names the action wanted by the same subject.
quero: The standard present form for yo has the stem quier. Simply attaching the regular ending to quer does not produce the required form.
Question 10
Complete the sentence for this meaning: We can help.
Nosotros ___ ayudar.
- puedemos
- podemos
Check the answer
Answer: podemos
puedemos: The stem change seen in puedo does not extend to nosotros in this pattern. Use podemos.
podemos: The we form keeps the stem vowel of poder and adds emos. The following infinitive ayudar stays unchanged because podemos already marks the subject.
Question 11
Complete the sentence for this meaning: I have two sisters.
Yo ___ dos hermanas.
- tengo
- tienen
Check the answer
Answer: tengo
tengo: Tengo is the present speaker form of tener. The two sisters are what the speaker has; their plural number does not control the main verb’s agreement.
tienen: Tienen would mean they have or you all have. The grammatical subject here is the single speaker.
Question 12
Complete the sentence for this meaning: My brother makes dinner.
Mi hermano ___ la cena.
- hago
- hace
Check the answer
Answer: hace
hago: Hago means I make or I do. The named subject is the speaker’s brother, requiring third person singular agreement.
hace: The subject is a single third person, so hacer becomes hace. The irregular speaker form hago is useful to know but does not belong with this subject.
Question 13
Complete the sentence for this meaning: I do not work on Sundays.
Yo no ___ los domingos.
- trabajo
- trabajar
Check the answer
Answer: trabajo
trabajo: No precedes the finite speaker form trabajo. Spanish keeps the ordinary present ending instead of adding an English style helper to the negative statement.
trabajar: The infinitive cannot replace the finite verb in this statement. Negation does not remove the need for a form that agrees with yo.
Question 14
Complete the sentence for this meaning: Do you normally eat here, using tú?
¿Tú ___ aquí normalmente?
- come
- comes
Check the answer
Answer: comes
come: Come fits usted, he, or she. The explicit subject tú requires comes in the pattern practiced here.
comes: The question uses the ordinary present form comes for tú. Punctuation and questioning intonation distinguish the question without an extra verb meaning do.
Keep the conversation going
What to practice next
Return to the production tasks after a break. Reconstruct your sentences without the models, compare the meaning and form, and repair any error by explaining its cause. Then use one sentence in a short exchange of your own.
