The standard word order (orden de palabras) in Spanish declarative sentences is Subject-Verb-Object (SVO). But there is a great degree of flexibility in this regard, with possibility of variations to show emphasis or highlight new information.

The subject typically comes before the verb in Spanish. But when the subject is a pronoun, it is most-commonly omitted from the sentence, because the verb conjugation reflects the subject. Subject pronouns are typically only used for emphasis or clarification.

While the standard word order puts the subject before the verb, in some cases the subject can come after the verb, creating a Verb-Subject(-Object) order. This is done:

The object most commonly comes after the main verb, but if the object is replaced by an object pronoun, it either comes before the conjugated verb or attaches to the end of an infinitive, participle, or imeprative verb form, if there is one.

Some verbs can have two objects: the direct object and the indirect object. In such cases, both objects appear after the verb, with the direct object appearing before the indirect object.

However, if these objects are replaced by their corresponding pronouns, they come before the conjugated verb, with the indirect object pronoun coming before the direct object pronoun.

If an infinitive, participle, or imperative verb is present, both objects attach to its ending with their natural order, and if that verb form is accompanied by a conjugated verb, the pronouns can come either before the conjugated verb or attached to the infinitive/participle/imperative.

It is also possible to place the object before the verb, even if it's a noun phrase, reversing the order of the sentence to Object–Verb–Subject. This is typically done to put emphasis on the object. In this case, a redundant object pronoun comes between the object and the verb to signal that the object is fronted. For example:

Descriptive adjectives mainly come after the nouns they describe. However, sometimes they are used before nouns for stylistic reasons, and some of them adopt a more subjective or evaluative sense when used before the noun. For example:

Adverbs have a high degree of flexibility with regards to their placement. However, the preferred position for an adverb modifying a verb is after the verb or its object (if there is one) or, in case of adverbs of frequency, before the verb.

If the adverb is modifying an adjective or another adverb, it comes directly before the adjective or adverb.
