Introduction
cometerás is a useful Spanish verb form to recognize when talking about future actions, mistakes, and learning experiences. It means you will commit or you will make, depending on the words around it. For example, a speaker might say that you will make a mistake while practicing a new skill, or that you will commit an error in a calculation. The exact English translation changes with the noun that follows, so learning common word combinations is important.
This form belongs to the verb cometer, which is often used with nouns such as error and equivocación. It also gives learners a clear example of how Spanish forms the simple future tense. The written accent mark tells you where to place the stress, and the ending shows that the speaker is addressing one person informally in most varieties of Spanish. In this guide, you will learn the meaning, pronunciation, grammar, and everyday use of cometerás, with simple examples to help you understand it and use it naturally.
Meaning and Definition
Cometerás is the second-person singular simple future form of the Spanish verb cometer. Its basic meaning is you will commit or you will make. It refers to an action that the speaker expects or predicts will happen later. The form usually addresses one person as tú, the familiar singular you used with friends, family members, classmates, and people with whom the speaker has an informal relationship.
The verb cometer often appears with a noun that names an error or an action. In English, we commonly say make a mistake, while Spanish commonly uses cometer un error. For that reason, a natural translation of cometerás in a sentence about a mistake is often you will make, not you will commit. With other nouns, commit may be the more suitable English choice. Always consider the full phrase rather than translating the verb by itself.
For example, cometerás un error means you will make a mistake. The future form does not necessarily say that the action is certain. Depending on the situation and the speaker’s tone, it can express a prediction, a warning, or an expectation. A teacher might use it gently to remind a student that mistakes are a normal part of practice. In another conversation, the same form may sound more direct, so context matters.
Spanish builds the simple future of many verbs by adding an ending to the infinitive. Cometer is a regular -er verb, so its infinitive stays complete and receives the future ending -ás for tú. This gives cometer + ás, written as cometerás. The same ending appears in forms such as aprenderás, meaning you will learn, and correrás, meaning you will run. The accent mark is part of the spelling and marks the stressed syllable.
The verb cometer comes from Latin committere, a verb with meanings connected to bringing or putting together and entrusting an action. Its modern Spanish uses have developed around carrying out or doing an act, often one that is an error. Learners do not need to know the Latin history to use the word correctly, but it helps explain why cometer is not a general replacement for every use of English make or do.
Keep the subject in mind, too. Cometerás is for one person addressed as tú. If you are talking formally to one person, Spanish usually uses usted cometerá. If you are talking to several people, the form may be ustedes cometerán or vosotros cometeréis, depending on the region. The form itself does not change for masculine or feminine subjects, because its ending refers to the person being addressed rather than their gender.
Usage and Example Sentences
The examples below show cometerás in common, safe contexts. Notice how the noun after the verb helps determine the most natural English translation. In several examples, English uses make even though the Spanish uses cometer.
Spanish: Si no revisas tus cuentas, cometerás un error de cálculo.
English: If you do not check your figures, you will make a calculation error.
Spanish: Al principio, cometerás algunos errores mientras aprendes a cocinar.
English: At first, you will make a few mistakes while learning to cook.
Spanish: Si respondes demasiado rápido, cometerás una equivocación.
English: If you answer too quickly, you will make a mistake.
Spanish: Cometerás menos errores si lees las instrucciones con calma.
English: You will make fewer mistakes if you read the instructions calmly.
Spanish: Durante el juego, cometerás algún error, y eso es parte de aprender.
English: During the game, you will make a mistake or two, and that is part of learning.
Spanish: Si cambias el orden de los pasos, cometerás un error en la receta.
English: If you change the order of the steps, you will make a mistake in the recipe.
Spanish: Con más práctica, cometerás menos errores al escribir en español.

Spanish: Cometerás una pequeña equivocación si no miras el mapa antes de salir.
English: You will make a small mistake if you do not look at the map before leaving.
These examples also show that the future tense can describe an expected result after a condition. The words si no, meaning if you do not, introduce a condition, while the future form describes what the speaker thinks may follow. In a friendly conversation, such a sentence can be advice rather than a firm prediction. Tone, facial expression, and the relationship between speakers all help communicate the intended meaning.
Synonyms, Antonyms, and Word Usage Differences
Several Spanish words are related to cometerás, but they are not interchangeable in every sentence. The best choice depends on the action and the noun. Cometer is especially common with error, errores, equivocación, and equivocaciones. These combinations are useful to learn as complete phrases because they sound natural and make translation easier.
Equivocarse means to be mistaken or to make a mistake. Unlike cometer, it is a pronominal verb, so it appears with a small pronoun that matches the subject. For example, te equivocarás means you will be mistaken or you will make a mistake. It often focuses on the person who gets something wrong, while cometer un error puts more focus on the error itself. Both can describe the same general situation, but their sentence structures differ.
Errar can also mean to make a mistake or to be wrong. It is understood in many Spanish-speaking regions, but it may sound more formal or literary than equivocarse in everyday conversation. A learner can use cometer un error for a clear, common expression or equivocarse for a natural way to say that someone is mistaken. The choice depends on the sentence: cometer normally takes a noun, while equivocarse works as a verb with a matching pronoun.
Hacer is the most general Spanish verb for to do or to make. It works in many ordinary phrases, such as hacer una pregunta, to ask a question, and hacer una tarea, to do an assignment. But Spanish speakers usually say cometer un error rather than hacer un error. This is a good reminder that expressions do not always match word for word between Spanish and English. Learn the usual combinations, not just a single English translation.
Realizar can mean to carry out, perform, or complete, and it often sounds more formal than hacer. It is useful for tasks and activities, but it is not usually the natural substitute in the phrase cometer un error. In other words, a verb may share part of the meaning of make or do without fitting the same noun. When in doubt, check a reliable dictionary example or notice how the word appears in a full sentence.
There is no simple opposite that works in every context. If cometerás means you will make a mistake, a possible opposite idea is you will get it right or you will avoid a mistake. Spanish could express that with acertarás, meaning you will get it right, or evitarás un error, meaning you will avoid a mistake. These are not direct antonyms of cometer, but they express a contrasting outcome. Choose the phrase that matches what you want to say.
Cometer can sometimes sound more serious than simply making a small mistake, especially when paired with nouns that describe a significant action. In everyday learning contexts, however, cometer un error is a routine phrase and does not automatically sound dramatic. A calm adjective such as pequeño, meaning small, or a learning context can make the intended sense clear. Pay attention to the noun and the surrounding sentence before deciding how serious the phrase sounds.
Pronunciation and Accent
The standard pronunciation of cometerás can be shown in IPA as /ko.me.teˈɾas/. It has four syllables: co-me-te-rás. The final syllable, rás, receives the main stress. Say the word as koh-meh-teh-RAHS, keeping the vowels clear and giving the last syllable a little more emphasis than the others.
The accent mark over á is essential. In Spanish, a word ending in a vowel, n, or s normally has stress on the next-to-last syllable if it has no written accent. The accent in cometerás shows that the stress falls on the final syllable instead. Without that written mark, the spelling would follow a different stress pattern, so the accent is not decorative. It helps readers pronounce the word correctly and distinguishes this future form from other possible forms.
The Spanish r in the final syllable is a single tap, similar to the light sound in the middle of the English word butter for many speakers. It is not the stronger rolled rr sound. The first c is pronounced like k in most Spanish accents. The final s is usually a clear s sound, although its exact strength can vary by region and speaking style.
A common learner mistake is to stress the second syllable, as if the word were pronounced koh-MEH-teh-rahs. Keep the strongest stress on rás. Another mistake is to leave out the accent when writing. Remember the future ending -ás: many tú forms in the simple future have this stressed ending, as in hablarás, aprenderás, and vivirás. Listening to native speakers and repeating the word in a full sentence can help make the rhythm feel natural.
Native Speaker Nuance and Usage Context
Native speakers often use cometerás when predicting that someone will make a mistake or when explaining what may happen next. It is common in advice, teaching, and conversations about learning. A tutor might say that a student will make some mistakes at first, then improve with practice. In this setting, the expression is ordinary and supportive rather than harsh.
The simple future can sound more definite than a present-tense phrase about what someone is going to do, but the difference depends on the region and context. Spanish speakers also use ir a plus an infinitive for future plans and predictions. For example, vas a cometer un error means you are going to make a mistake. Cometerás can sound like you will make a mistake, sometimes with a more direct or formal tone, though it is also used naturally in everyday speech.
The form addresses one person informally as tú. In many regions, tú is familiar and personal, while usted is used to show respect or distance. A speaker addressing someone as usted would say cometerá, not cometerás. In Spain, speakers may use vosotros for a familiar group, producing cometeréis. Across much of Latin America, ustedes is common for groups in both familiar and polite situations, and its form is cometerán.
Even when speaking to one person, a subject pronoun is often left out because the verb ending already gives a useful clue. A speaker can say cometerás un error without saying tú. Adding tú can create emphasis or contrast, as in tú cometerás el primer error, but it is not required in an ordinary sentence. This flexibility is a normal feature of Spanish and helps speech sound less repetitive.
In natural conversation, the word is often softened by the way a speaker frames the idea. Phrases such as al principio, at first, or con la práctica, with practice, show that mistakes are expected during learning and can improve over time. The verb itself does not say whether a mistake is large or small. The noun, descriptive words, tone, and surrounding situation carry that extra meaning.
For learners, the most helpful habit is to remember a few complete combinations: cometer un error, cometer errores, and cometer una equivocación. Then practice changing the subject and tense. For example, cometerás describes what tú will do, while cometerás menos errores means you will make fewer mistakes. This kind of pattern practice helps you use the verb without pausing to translate each word separately.
Conclusion
Cometerás is the simple future form of cometer for tú, and its basic meaning is you will commit or you will make. In common expressions such as cometer un error, the most natural English translation is usually you will make a mistake. The noun that follows the verb is an important clue, so it is useful to learn common word combinations rather than depend on one fixed translation.
To say the word clearly, divide it into co-me-te-rás and stress the final syllable. The accent mark over á shows that stress and should always be included in writing. Remember that the form speaks to one person informally; usted and plural subjects require different endings. With regular practice, you can recognize cometerás in predictions, advice, and conversations about learning. Understanding this form also gives you a practical model for building other Spanish future verbs and expressing what may happen next.
