fijarlas

Fijarlas is the non-finite form formed by the Spanish verb fijar in the infinitive plus the feminine plural direct object pronoun las. The phrase literally means “to fix them,” with las referring to feminine plural nouns (for example, las piezas, las etiquetas). The function of fijarlas is to indicate the action of fixing, attaching, or securing those feminine plural items, depending on the context.

In usage, fijarlas can express several senses tied to fijar, including attaching objects to a surface, securing components with fasteners, or establishing a state or decision. It is commonly used with auxiliary verbs or in constructions that require an infinitive: voy a fijarlas, tengo que fijarlas, o las voy a fijar. When forming commands or polite forms, the dependent pronoun may appear in different positions: Fíjalas (tú), Fíjelas (usted). The form also appears in gerund and participial constructions: fijándolas (fixing them) and fijadas (fixed them).

Grammatical notes: the pronoun las must agree in gender and number with the direct object; its placement follows standard Spanish clitic rules and can attach to an infinitive or a conjugated verb, or appear before a conjugated auxiliary. Because it involves a clitic, stress and accent patterns may vary with the surrounding words and tenses.

Examples:

- Necesito fijarlas a la pared. (I need to fix them to the wall.)

- Vamos a fijarlas con tornillos. (We are going to fasten them with screws.)

- Debemos fijarlas en la fecha acordada. (We must set them on the agreed date.)
