definirlas

Definirlas is the combination of the verb definir (to define) and the direct object pronoun las (them, feminine plural) in Spanish. It represents the infinitive form with an attached clitic pronoun and is used when the referent is feminine plural. This construction is common when the infinitive functions as a non-finite verb in a sentence or clause.

Usage and function: Definirlas can appear in sentences where the action is described in the infinitive. It can serve as the subject or the complement of a sentence, depending on the context. For example, in sentences like Definirlas es importante (Defining them is important) or Tenemos que definirlas (We have to define them), the phrase includes la forma infinitiva with the attached pronoun. The pronoun can also attach to a gerund: Definiéndolas, el equipo avanzó (Defining them, the team progressed).

Pronoun placement and agreement: The direct object pronoun las agrees with feminine plural nouns that it refers to. If the sentence involves masculine or mixed objects, a different pronoun would be used (los). When the action is expressed with a finite verb, the pronoun is usually placed before the conjugated verb or attached to an infinitive in a related construction (Definirlas vs. Las definimos). With a gerund, the pronoun attaches as Definiéndolas.

Examples:

- Definirlas es necesario para avanzar en el proyecto.

- Vamos a definirlas mañana.

- No las defino todavía; necesito más datos.

- Definirlas correctamente requiere criterios claros.

Etymology and related forms: Definir comes from Latin definire. The article illustrates a typical use of clitic pronouns with non-finite verbs in Spanish. See also: pronombres clíticos, uso de infinitivos y gerundios en español.
