In Spanish, the most common form of an affirmative sentence follows the pattern subject + verb + complements. The subject says who performs the action or who is being spoken about. The verb expresses the action or the state. After the verb, the complements appear that complete the idea: object, place, time, manner, or quantity. In a sentence like María compra pan en la tienda, María is the subject, compra is the verb, and pan en la tienda completes the sense. This order connects to what you see in Estructura de la oración and with the basic pattern of Oraciones simples.

Many times the subject does not appear in writing because the verb form already indicates who performs the action. In Trabajo en casa, the ending of trabajo shows that the subject is yo. In Viven aquí, the verb indicates they, they all, or you all depending on the context. The subject is also omitted when it is already understood from what was said before: Ana llega tarde. Trae café para todos. In the second sentence, the subject remains Ana. When the subject is not expressed, the word order still depends on the verb and the complements, as in Orden de palabras.

Complements that close the sentence

Usage	Explanation
Forma verbal clara	Se puede omitir el sujeto cuando la forma del verbo ya muestra quién realiza la acción.
Contexto compartido	Se omite el sujeto cuando el contexto deja claro de quién se habla.
Énfasis en la acción	Se deja fuera el sujeto cuando importa más la acción que la persona.

Locatives, times, and manner complements tend to come after the verb and the direct object. Lugar answers where, tiempo when, and modo how. Therefore, their natural position is at the end of the sentence: Compramos frutas en el mercado, Salimos mañana, Habla con calma. If there are several complements, the usual order is verb + object + time + place + manner, though not all need to appear. In Leí el libro ayer en casa con tranquilidad, each complement contributes a different part of the scene and ends the sentence naturally.

Natural position of adverbs

Idea
Adverbs are usually placed near the verb.
Adverbs can also go at the end of the sentence.
An adverb can separate two ideas of the same rhythm when it accompanies the main action.

Adverbs that express frequency, intensity, doubt, or manner tend to be placed near the verb. Siempre, ya, todavía, también, muy and bien are often heard alongside the verb form: Siempre come temprano, Ya terminó, Habla muy bien. When the adverb modifies the whole action, it can also go at the end: Llegó tarde. The placement changes the focus: near the verb, the adverb directly accompanies the action; at the end, it sounds more emphatic and puts the main information first. This relationship with the verb is useful in the sentences you also study in Oraciones interrogativas and Oraciones exclamativas.

Place of object pronouns

Idea
In an affirmative sentence the object pronoun usually goes before the conjugated verb.
With an infinitive the pronoun can join at the end of the verb.
With two verbs the pronoun can be placed next to the infinitive to sound natural.

Direct and indirect object pronouns are usually placed before the conjugated verb: Lo vi, Le escribí una carta, Los invité. If the verb is in an infinitive, the pronoun can attach to the end: Quiero verlo, Voy a decirle la verdad, Prefiero invitarlos. They also attach to the gerund and to the affirmative imperative, but here the key rule is the affirmative with the infinitive. When there are two pronouns together, the indirect goes before the direct: Se lo dije. This placement makes clear who receives the action and what receives it.

Order with initial verb for emphasis

Idea
En una oración afirmativa el pronombre de objeto suele ir antes del verbo conjugado.
Con un infinitivo el pronombre puede unirse al final del verbo.
Con dos verbos el pronombre puede colocarse junto al infinitivo para sonar natural.

Sometimes the verb appears before the subject to emphasize the action or to create a more narrative or literary tone. Instead of Mi hermano llegó, you can say Llegó mi hermano to give more weight to the act of arriving. In narration, this order often appears when the speaker wants to present the event first and then the person: Entraron tres niños al aula, Apareció una solución inesperada. The subject remains the same, but it is placed at the end and receives less protagonism than the action. This change does not alter the sentence structure, it only reorganizes the information to direct attention.

Be, estar and parecer with attribute

Usage	Explanation
Énfasis en la acción	Se coloca el verbo antes del sujeto para destacar lo que sucede.
Tono literario	Este orden se usa para dar un tono más literario o más expresivo.
Impacto narrativo	El verbo al inicio sirve para atraer la atención desde la primera palabra.

With ser, estar, and parecer, the sentence does not present an action but a relationship between the subject and an attribute. The scheme is subject + copulative verb + attribute. That attribute can describe a quality, a condition, a profession, a place, or an impression: El cielo está gris, Laura es médica, La sopa parece caliente. Ser identifies or classifies, estar presents a state or situation, and parecer expresses appearance. In these sentences, the attribute completes the subject’s idea just as in Oraciones subordinadas adds information without breaking the main sentence.

Insertion of subordinate clauses into the sentence

Idea
A subordinate clause can add extra information to the main sentence.
The main sentence keeps the basic order even when a subordinate clause appears.
The subordinate clause can go at the beginning of the sentence to change the focus.

An affirmative sentence can include another sentence that depends on it to provide more information. The main sentence maintains the central meaning and the subordinate adds detail, cause, time, intention, or explanation. In Sé que vienes mañana, sé is the main part and que vienes mañana completes its content. In Saldré cuando termine el trabajo, the time clause marks the moment of the main action. The general order remains clear: the main clause supports the structure and the subordinate is integrated as a complement or explanation. In longer statements, the relationship between both sentences organizes the message without changing the affirmative character of the whole sentence.

Inserción de subordinadas en la oración

Idea
Una subordinada puede añadir información extra a la oración principal.
La oración principal mantiene el orden básico aunque aparezca una subordinada.
La subordinada puede ir al principio de la oración para cambiar el foco.
