diferenciarlas

Diferenciarlas is a Spanish infinitive construction formed from the verb diferenciar with the clitic pronoun las attached, indicating that the object to be distinguished is feminine and plural. The phrase is used to express the action of distinguishing two or more feminine plural items, such as especies, variedades, conceptos, or categorías, especially when those items have been previously named or implied in context.

Grammatically, diferenciar is a transitive verb, and the pronoun las serves as the direct object corresponding to feminine plural nouns. The pronoun can attach to the infinitive or to related verbal forms: for example, debemos diferenciarlas, vamos a diferenciarlas, o están diferenciándolas. The same pattern applies with other pronouns to reflect gender and number, such as diferenciarlos (masculine plural) o diferenciarlas (feminine plural).

Usage and applications of the expression occur across several domains. In education and communication, it appears when contrasting items to clarify their distinct features. In science and data analysis, it is used to describe the process of classifying or separating groups based on selected criteria. Proper use often involves identifying distinguishing features, comparing alternatives, and selecting criteria that reliably separate the items in question.

Examples:

Es necesario diferenciar las especies y diferenciarlas con base en rasgos morfológicos y genéticos. Es difícil diferenciarlas a simple vista. El informe propone diferenciar las categorías y diferenciarlas mediante criterios objetivos.
