--- title: "Es in Elementary Latin" description: "\"Es\" is the 2nd-person singular form of sum, used with linking verbs to name or describe the subject in Elementary Latin sentences." canonical: "https://fiveable.me/elementary-latin/key-terms/es" type: "key-term" subject: "Elementary Latin" unit: "Unit 3" --- # Es in Elementary Latin ## Definition "Es" is the second-person singular form of *sum*, the Latin verb “to be.” In Elementary Latin, it links a subject to a noun or adjective, as in *tu es magister* or *es laetus*. ## What It Is "Es" is the Latin form of “you are.” It is the second-person singular present tense of *sum*, the verb that means “to be.” In an Elementary Latin class, you use it when the subject is singular and the speaker is talking directly to that person. Because *sum* is irregular, *es* does not follow the normal pattern you see in many other verbs. That is one reason it shows up early in Latin lessons and keeps coming back. Once you know *es*, you can recognize simple identity and description statements without trying to force them into action-verb logic. In a sentence, *es* acts as a linking verb. It does not describe an action that gets done to something else. Instead, it connects the subject with a predicate nominative or predicate adjective in the nominative case. For example, *tu es magister* means “you are a teacher,” and *tu es laetus* means “you are happy.” In both cases, *es* ties the subject to what completes the thought. That linking function matters because Latin word order can be flexible. You may see the subject, *es*, and the complement in different positions, but the meaning stays the same as long as the grammar matches. When you see *es*, ask: who is being described, and is the next word naming that person or describing them? You also need to watch for agreement. Since *es* is singular, it goes with one person, not a group. It is different from forms like *estis* for “you all are.” In beginner Latin, that number clue helps you sort out who the sentence is about before you translate anything else. ## Why It Matters "Es" shows up constantly in the kind of short Latin sentences beginners translate, especially identity statements, class descriptions, and simple questions. If you can spot it quickly, you can tell that the sentence is not about an action but about a state of being or a description. This term also pulls together several grammar ideas at once. You have to recognize *sum* as an irregular verb, notice that *es* is singular, and then decide whether the word after it is a predicate nominative or a predicate adjective. That is a basic Latin reading skill, not just a vocabulary item. It matters for sentence parsing too. Latin does not always arrange words in the same order English does, so *es* can help you identify the subject and the complement even when the sentence feels scrambled at first. If you can read *puella es* or *es poeta*, you are already doing real translation work, not just word matching. A lot of early Latin writing and classroom practice uses forms of *sum* because they are the cleanest way to practice case agreement. Once you can handle *es*, you are better prepared for longer sentences where the verb is not obvious and the predicate comes before the subject. ## Connections ### Sum *Es* is one form of *sum*, so learning the full verb helps you place it in the larger present tense pattern. Beginners often memorize *sum, es, est, sumus, estis, sunt* as a core set because these forms appear constantly in short reading passages and grammar drills. ### Predicate Nominative After *es*, a noun can rename the subject instead of receiving an action. In *tu es magister*, *magister* is a predicate nominative because it identifies who “you” are, and it stays in the nominative case to match the subject. ### Linking Verb *Es* links the subject to a complement rather than showing action. That means you translate it with “is,” “are,” or “am” depending on the subject, and then focus on whether the complement is naming or describing. ### [adiectivum](/elementary-latin/key-terms/adiectivum) When *es* is followed by an adjective, the adjective describes the subject. Because adjectives agree with the nouns they modify, you look for matching case, number, and gender before you translate the description. ## On the AP Exam A quiz question may give you a short Latin sentence and ask you to identify the verb, translate it, or explain why a noun or adjective is in the nominative. When you see *es*, the task is usually to recognize second-person singular and then decide whether the next word is a predicate nominative or a predicate adjective. In translation exercises, that often means turning *es* into “you are” and checking whether the rest of the sentence names or describes the subject. If the sentence uses *sum* forms in different persons, you may also need to match each form to the correct English pronoun. ## -ēs vs estis *Es* and *estis* are easy to mix up because they both come from *sum* and both translate with “you are” in English. The difference is number: *es* is singular, so it means one person is being addressed, while *estis* is plural and means more than one person is being addressed. ## Key Takeaways - "Es" means “you are” and is the second-person singular form of *sum*. - In Latin, *es* acts as a linking verb, not an action verb. - The word after *es* is often a predicate nominative or predicate adjective in the nominative case. - Because Latin word order can vary, *es* helps you identify the subject-complement structure of a sentence. - If you can recognize *es* quickly, simple Latin sentences become much easier to translate and parse. ## FAQs ### What is es in Elementary Latin?
