intrusa

Intrusa is the feminine form of the noun intruso in Spanish, Portuguese, and Italian. It refers to a person who enters a space or situation without permission or invitation, i.e., a female intruder. The masculine form is intruso, so intrusa corresponds to a female intruder or an uninvited participant. The term derives from Latin intrusus, the past participle of intrudere, meaning to thrust in.

In everyday language, intrusa is used to describe an uninvited guest, a nosy person, or an unwelcome participant in a discussion or event. It can also be used metaphorically to denote something that intrudes where it is not wanted, for example a presence that intrudes into a private space. In formal or legal registers, related terms such as intrusión (Spanish), intrusione (Italian), or intrusão (Portuguese) are more common, but intrusa remains widely understood in colloquial speech and literature.

Examples in different languages illustrate its usage: Spanish — "Una intrusa entró sin llamar"; Portuguese — "Uma intrusa entrou sem ser convidada"; Italian — "L'intrusa è entrata senza essere invitata." The word thus signals an unwelcome entry, whether literal or figurative.
