influyen

Influyen is the present indicative third-person plural form of the Spanish verb influir, meaning "they influence." It is used when the subject is plural and exerts influence on a person, a group, an idea, or a situation. The infinitive is influir, and the noun form is influencia.

The verb influir is irregular in some forms. In the present indicative, the forms are: yo influyo, tú influyes, él influye, nosotros influimos, vosotros influís, ellos influyen. The verb belongs to a class of -uir verbs that alternate with a stem change in several tenses. The corresponding past tenses and the present subjunctive use related stems such as influ- or influy-.

Usage notes: In contemporary Spanish, influyen is commonly followed by en to indicate the area of impact, as in "Las redes sociales influyen en la opinión pública." It can describe effects on opinions, decisions, behavior, or trends. While influence can be strong, the word does not imply direct control. For naming the phenomenon or the actor, related nouns like influencia, influenciador (or influencer in modern usage) are used.

Etymology: influir comes from Latin influere, from in- plus fluere, "to flow in." The noun influencia derives from Latin influentia, with a similar semantic trajectory. The term has long been used to describe how outside factors can steer perceptions and actions.
