Introduction
nadaban is a Spanish verb form you may hear when people describe what a group of people or animals was doing in the water. It means they were swimming, or they used to swim. Because it describes an action in the past, it is especially useful for telling stories, talking about childhood memories, and setting a scene. You may see it in a sentence about children at a pool, friends at a lake, or fish moving through a river.
Learning this form also gives you a practical introduction to the Spanish imperfect tense. The imperfect helps speakers talk about past actions that continued for a while, happened regularly, or were in progress when another event took place. In this guide, you will learn how the word is built, how it differs from similar past-tense forms, and how to pronounce it. Simple examples will help you recognize it and use it naturally in conversation.
Meaning and Definition
nadaban is the third-person plural form of the verb nadar, which means to swim. In English, it usually translates as they were swimming or they used to swim. The subject can be a group of people, animals, or things that are understood to be swimming. For example, the subject might be some children, the guests, the ducks, or the fish.
The form combines two pieces: the verb stem nad- and the imperfect ending -aban. Spanish verbs ending in -ar use this ending for the third-person plural imperfect. The subject pronoun ellos means they, and ellas means they when referring to a feminine group. However, Spanish often leaves out these pronouns because the verb ending already gives useful information about the subject.
The imperfect is used for past actions viewed as ongoing, repeated, or part of a background situation. It does not usually tell the reader exactly when the action began or ended. If you say that a group nadaban in the afternoon, you could be describing a repeated habit or an activity that was underway at that time. The surrounding sentence or conversation makes the intended meaning clear.
Compare this with the preterite form nadaron, which commonly describes a completed swimming event. For example, nadaron durante una hora means they swam for an hour, presenting the activity as a finished event. By contrast, nadaban durante el verano can describe what they used to do during the summer. The imperfect focuses on the ongoing or habitual nature of the past action.
The verb nadar comes from Latin natare, meaning to swim. The same basic idea remains in modern Spanish. Its forms follow a regular pattern, so once you know how one regular -ar verb changes in the imperfect, you can recognize many others. For example, cantaban means they were singing or they used to sing, and jugaban means they were playing or they used to play.
In a dictionary, you will usually find the infinitive nadar, not the conjugated form. When you encounter nadaban in a sentence, look for a plural subject and consider whether the context describes a past routine, an ongoing activity, or background information. This simple check will help you understand the form without needing to translate each part separately.
Usage and Example Sentences
The examples below show how nadaban works in different settings. Notice that English may use either were swimming or used to swim, depending on the context.
Spanish: Los niños nadaban en la piscina después de la escuela.
English: The children used to swim in the pool after school.
Spanish: Cuando llegamos a la playa, varias personas nadaban cerca de la orilla.
English: When we arrived at the beach, several people were swimming near the shore.
Spanish: Mis primos nadaban en el lago todos los veranos.
English: My cousins used to swim in the lake every summer.
Spanish: Los patos nadaban tranquilamente por el estanque.
English: The ducks were swimming peacefully across the pond.
Spanish: A esa hora, los estudiantes nadaban en la piscina del centro deportivo.
English: At that time, the students were swimming in the sports center pool.
Spanish: De pequeños, mis hermanos nadaban antes del desayuno.
English: When they were young, my brothers used to swim before breakfast.
Spanish: Mientras el sol se ponía, los visitantes nadaban en el mar.
English: While the sun was setting, the visitors were swimming in the sea.

Spanish: Antes de la cena, mis amigos y yo nadábamos en la piscina.
English: Before dinner, my friends and I used to swim in the pool.
The last example uses nadábamos, not nadaban, because its subject is we. This is a useful contrast: nadaban refers to they, while nadábamos refers to we. The accent mark in nadábamos also shows where the stress falls, whereas nadaban does not need a written accent.
Synonyms, Antonyms, and Word Usage Differences
There is no perfect synonym for nadaban that keeps every part of its meaning. You can sometimes say se movían en el agua, meaning they were moving in the water, but this describes motion without clearly saying that the subjects were swimming. The verb flotaban means they were floating. It may describe something resting on the water, so it is not a direct replacement for swimming.
The present-tense form nadan means they swim or they are swimming now. It describes the present rather than the past. The infinitive nadar means to swim and is used after expressions such as les gusta nadar, meaning they like to swim. These forms share the same verb but do different jobs in a sentence.
The most important past-tense comparison is nadaron. Both it and nadaban can refer to past swimming, but they present the action differently. Use nadaron when you view the action as a complete event, often with a clear end or time limit. Use nadaban when you want to emphasize a repeated habit, an action in progress, or the background to another event.
For instance, nadaron en la piscina el sábado presents the swimming as something the group did on Saturday. Nadaban en la piscina cuando empezó a llover means they were swimming in the pool when it started to rain. The second sentence places one past action inside another scene: the swimming was already underway when the rain began.
Spanish has several useful opposites depending on what you want to express. Salían del agua means they were getting out of the water, while se hundían means they were sinking. These are not direct grammatical opposites, but they describe movement away from or downward in the water instead of swimming through it. Choose the verb that matches the actual action, rather than looking for a single fixed opposite.
Remember that the subject matters too. Nadaba can mean he, she, or you were swimming, depending on context. Nadábamos means we were swimming. Nadaban means they or you all were swimming. In many varieties of Spanish, speakers use ustedes for you all, and it takes the same verb form as they. In Spain, vosotros nadabais is commonly used for an informal group you.
To choose the right form, first identify who is swimming, then decide whether the action is present or past. If it is past, ask whether you are describing a habit or an activity in progress, or presenting a completed event. This small sequence of questions helps you select between nadan, nadaban, and nadaron with greater confidence.
Pronunciation and Accent
The pronunciation of nadaban can be shown in IPA as /naˈðaβan/. A simple guide for English speakers is nah-DAH-bahn, with the strongest emphasis on the middle syllable. The word has three syllables: na, da, and ban. Say each one clearly, keeping the vowels short and steady rather than turning them into long English-style vowel sounds.
The letter d between vowels is softer in Spanish than the strong d sound many English speakers expect. In much of the Spanish-speaking world, it is pronounced with the tongue lightly touching or approaching the area behind the upper teeth. The letter b is also soft between vowels. It may sound closer to a gentle b or v, depending on the speaker and the surrounding sounds. Do not overemphasize either consonant.
The stress falls on the next-to-last syllable, da. There is no written accent mark because Spanish words ending in a vowel, n, or s normally receive stress on the next-to-last syllable. The spelling follows this regular pattern. By contrast, nadábamos has a written accent because its stress pattern does not follow the usual rule for a word ending in s.
A common mistake is to stress the first syllable or the final syllable. Practice saying nah-DAH-bahn at an even pace. Another mistake is to pronounce the Spanish a like the vowel in the English word day. Spanish a is more like the open sound in father. Listening to native speakers and repeating the word in a full sentence can help you hear its natural rhythm.
Native Speaker Nuance and Usage Context
Native speakers commonly use nadaban when describing an earlier scene or a past routine. It fits naturally in stories about holidays, childhood, sports, and time spent with family. A speaker might use it to set a scene before explaining what happened next, as in: Los niños nadaban cuando llegó su profesora, meaning the children were swimming when their teacher arrived.
The word itself is neutral. It is appropriate in casual conversation, school assignments, travel stories, and more formal descriptions. The level of formality usually comes from the rest of the sentence, not from this verb form. People use it in the same way whether they are talking with friends or writing a straightforward account of past activities.
Context often determines whether the best English translation is were swimming or used to swim. A time expression such as todos los sábados, meaning every Saturday, suggests a repeated habit. A phrase such as cuando entré, meaning when I entered, often points to an activity that was already in progress. Spanish speakers do not need to add a separate word for was or used to; the imperfect form and the surrounding details communicate the idea.
Spanish also frequently leaves out the subject pronoun. Instead of saying ellos nadaban, a speaker can simply say nadaban when it is already clear who the group is. A pronoun may be included to make a contrast or add emphasis. For example, ellos nadaban, pero nosotros caminábamos means they were swimming, but we were walking. The pronouns make the difference between the two groups clear.
When listening, do not assume that every plural subject is a group of people. The verb can refer to animals or other subjects that swim as well. The noun or earlier conversation tells you what the subject is. Paying attention to these nearby clues is an important part of understanding natural Spanish, where repeated pronouns are often omitted.
Conclusion
nadaban is the imperfect form of nadar for they or you all. It means they were swimming or they used to swim, depending on the context. Spanish speakers use it to describe an activity in progress, a repeated past habit, or background information in a story. The form is regular: the stem nad- combines with the imperfect ending -aban.
When choosing between nadaban and nadaron, think about how you want to present the past action. The imperfect describes an ongoing or repeated activity, while the preterite often presents a completed event. For pronunciation, remember the three syllables and stress the middle one: nah-DAH-bahn. There is no accent mark because the word follows the usual Spanish stress rule. With these patterns in mind, you can recognize the word in stories and use it to talk about swimming routines or scenes from the past. Learning this form also makes it easier to understand other regular verbs in the Spanish imperfect.
