Intruso

Intruso is a Spanish noun and adjective used to describe a person who enters a place or situation without permission or proper invitation. The term typically carries a sense of unauthorized intrusion into physical space, social groups, or private affairs. As an adjective, intruso can describe actions or individuals that are perceived as intrusive or unwanted.

Etymology and usage

The word derives from Latin intrusus, from intrudere, meaning to thrust in. In everyday language, intruso is applied to someone who breaches boundaries—whether breaking into a home, attending a private event without invitation, or inserting themselves into conversations or communities where they are not welcome. The related adjective intrusivo conveys the broader idea of being intrusive or meddlesome.

Contexts and meanings

In a social or physical context, an intruso is someone who trespasses or infringes on others’ privacy. Legally, the term is often used informally to describe a trespasser or a person who commits unauthorized entry, though formal charges would rely on specific statutes such as trespass or invasion of privacy. In computing and information security, intruso can refer to an unauthorized user who gains access to systems or data, with related terms like intrusión (intrusion) and intrusivo (intrusive) common in technical discourse. In ecology, some uses describe non-native organisms that invade ecosystems, though the more formal term is usually especies invasoras or organismos invasores.
