Introduction
Learning Spanish verb structures can be challenging, especially when dealing with similar expressions that seem to mean the same thing. Two of the most commonly confused verbs for English speakers are empezar a and comenzar a. While these phrases are often used interchangeably in casual conversation, understanding their subtle differences, proper conjugation, and common mistakes will help you communicate more naturally and accurately in Spanish. This article explores the most frequent errors learners make with these verbs and provides clear guidance on how to use them correctly.
Understanding Empezar and Comenzar
Basic Definitions and Similarities
Both empezar and comenzar translate to start or begin in English. They are nearly synonymous and can often be used interchangeably in most contexts. The word empezar comes from the Latin prefix em- combined with the word for beginning, while comenzar derives from the Latin com- meaning together, plus the root for beginning. In modern Spanish, the distinction between the two is minimal in everyday speech.
The key structural element you need to understand is that both verbs require the preposition a when followed by an infinitive verb. This is where many learners make their first mistake. The construction is not simply empezar or comenzar followed directly by another verb. Instead, you must include the a between them, creating the phrase empezar a or comenzar a.
Regional Usage Differences
While both verbs are understood throughout the Spanish-speaking world, there are notable regional preferences. In Spain, empezar is generally more common in everyday conversation. In Latin America, both terms are used with roughly equal frequency, though some regions show preferences for one over the other. However, this regional difference should not concern you greatly as a learner. Both are correct, and native speakers will understand either version without any confusion.
The Essential Preposition A
Why A Is Required
The most critical element of using empezar a and comenzar a correctly is remembering the preposition a. In Spanish, these particular verbs function as what linguists call bridge verbs or control verbs. They bridge the main action with the action that follows, and this bridge requires the preposition a. Without it, the sentence is grammatically incorrect, even though Spanish speakers might understand your intention from context.
The structure follows this pattern: Subject + empezar/comenzar + a + infinitive verb. For example, you would say Voy a empezar a estudiar instead of Voy a empezar estudiar. The second version, while sometimes heard in very casual speech, is not standard Spanish.
When A Might Be Omitted
In extremely informal or colloquial Spanish, particularly in certain regions, the preposition a might occasionally be dropped. However, this is a regional variation that should not be imitated in formal writing or when learning Spanish properly. As a learner, you should always include a to maintain grammatical correctness and clarity. Your Spanish teachers and native speakers in formal settings will expect proper usage of this preposition.
Conjugation Patterns and Common Mistakes
Regular Conjugation of Empezar
The verb empezar is an irregular stem-changing verb in the present indicative tense. Specifically, it follows the e-to-ie pattern, meaning the e in the stem changes to ie in conjugated forms where the stress falls on the stem. Here is the present tense conjugation:
Yo empiezo
Tú empiezas
Él/ella/usted empieza
Nosotros/nosotras empezamos
Vosotros/vosotras empezáis
Ellos/ellas/ustedes empiezan
A common mistake students make is forgetting the stem change and conjugating the verb as if it were regular, saying yo empezo or él empieza incorrectly. Remember that when empezar a is used, the e becomes ie in the first, second, and third persons singular, plus the third person plural.
Regular Conjugation of Comenzar
The verb comenzar follows the exact same stem-changing pattern as empezar. It is also an e-to-ie verb. The conjugation is as follows:
Yo comienzo
Tú comienzas
Él/ella/usted comienza
Nosotros/nosotras comenzamos
Vosotros/vosotras comenzáis
Ellos/ellas/ustedes comienzan
Notice that in the first and second person plural forms, nosotros/as and vosotros/as, the stem change does NOT occur. This is because the stress in these forms falls on the ending, not the stem. This is a frequent error for learners who may apply the stem change to all conjugations. Always remember that the stem change only applies to stressed syllables.
Incorrect Conjugation Examples
One of the most common mistakes occurs when learners forget about stem-changing patterns altogether. Incorrect forms include yo empezo, yo comienzo pronounced with the e sound, or él empieza with regular conjugation. The correct forms must always show the ie diphthong in the appropriate positions. Another mistake involves overextending the stem change to the nosotros form, creating empiezamos or comiezamos, which are incorrect. The nosotros form should always be empezamos and comenzamos without the stem change.
Proper Usage in Different Contexts
Using Empezar A with Action Verbs
The most straightforward use of empezar a occurs when you want to express the beginning of an action. For example, Empiezo a correr cada mañana means I start running every morning. The infinitive verb that follows a describes the action that is beginning. This pattern applies to any action you want to describe: Comenzamos a preparar la cena means We start preparing dinner. The infinitive preparar is the action being initiated by the subject.
Common infinitive verbs used with empezar a and comenzar a include hablar (to speak), escribir (to write), leer (to read), trabajar (to work), aprender (to learn), and buscar (to look for). Any action verb can follow these constructions, provided it is in the infinitive form.
Time Expressions and Context
These verb constructions are frequently accompanied by time expressions that indicate when the action begins. Phrases like ahora (now), mañana (tomorrow), la próxima semana (next week), or a las tres (at three o’clock) can all pair nicely with empezar a and comenzar a. For instance, Mañana comienzo a trabajar en mi nuevo proyecto means Tomorrow I start working on my new project.
Another common pairing involves using these verbs in the past tense to describe when something began. Empecé a aprender español hace dos años means I started learning Spanish two years ago. This construction is extremely common in everyday conversation and storytelling.
Common Mistakes to Avoid
Forgetting the A Preposition
The single most common error learners make is omitting the preposition a entirely. You might hear yourself or other learners saying Empiezo estudiar or Comienzan trabajar, but these are incorrect. The proper forms require the a: Empiezo a estudiar and Comienzan a trabajar. This mistake is so common that it’s worth drilling repeatedly in practice.
Confusing With Other Prepositions
Some learners mistakenly use other prepositions with these verbs. Using de instead of a, for instance, creates an error. You should never say Empiezo de estudiar. Similarly, using en is incorrect: Comienzan en trabajar is not proper Spanish. Only a is the correct preposition for these particular verbs.
Mixing Tenses Incorrectly
Another mistake occurs when learners use the wrong tense for either the main verb or the infinitive. Remember that only the main verb empezar or comenzar conjugates and changes tense. The verb that follows a must always remain in the infinitive form, regardless of the tense of the main verb. For example, in the past tense, you would say Comenzó a hablar, not Comenzó a hablaba. The infinitive hablar does not conjugate.
Forgetting Stem Changes
As mentioned earlier, failing to apply the e-to-ie stem change results in incorrect conjugations. This is particularly problematic in the present tense. Saying yo empezo or él comieza shows a fundamental misunderstanding of how these verbs conjugate. Practice the stem-changing pattern until it becomes automatic.
Practical Examples and Sentences
Present Tense Examples
Empiezo a entender las reglas gramaticales means I start understanding the grammar rules. Ella comienza a cantar en el concierto means She starts singing in the concert. Ustedes empiezan a practicar español todos los días means You all start practicing Spanish every day. These examples show proper stem changes in the first, third, and third person plural forms, with the preposition a properly included.
Past Tense Examples
Comenzamos a estudiar a las ocho de la noche means We started studying at eight in the evening. Empecé a trabajar en la empresa hace cinco años means I started working at the company five years ago. Ellos comenzaron a vivir aquí el año pasado means They started living here last year. Notice that in the preterite tense, the stem change affects only the yo form in empezar, while comenzar has no stem change in the preterite.
Future and Conditional Examples
Comenzaré a aprender piano el próximo mes means I will start learning piano next month. Si tuviera tiempo, empezaría a escribir un libro means If I had time, I would start writing a book. In the future and conditional tenses, these verbs do not show stem changes, making them simpler to conjugate correctly.
Conclusion
Mastering the use of empezar a and comenzar a is essential for intermediate Spanish learners. The key takeaways are remembering the mandatory preposition a, correctly applying the e-to-ie stem change in present tense forms, and ensuring the following verb remains in the infinitive regardless of tense. While these verbs are nearly identical in meaning and can be used interchangeably, consistent proper usage demonstrates grammatical competence and enhances your credibility as a Spanish speaker. Practice these constructions regularly in writing and conversation until they feel natural. With focused attention to the common mistakes outlined in this article, you will quickly master these important verbs and communicate more effectively in Spanish.
