Anexo

Anexo is a term used in Spanish and Portuguese with several related senses centered on the idea of being joined or added to something else. In general usage, anexo denotes something that is attached, appended, or included with another item, rather than standalone.

In architecture and urban planning, an anexo is a secondary building or wing connected to a principal structure. Anexos are common in schools, hospitals, offices, and residential complexes, where they house offices, classrooms, or storage while sharing access with the main building.

In documents, administration, and law, an anexo refers to material that is added to a primary document, such as an annex, appendix, or attachment. It is often designated with labels like Anexo I, Anexo II, and may constitute contractual schedules, technical specifications, or supporting information.

In digital communication, an anexo is used to mean an email attachment or other appended files.

Etymology: the word derives from Latin annexus or anexus, meaning joined or linked, and entered Spanish and Portuguese through the development of the verbs anexar. See also annex, attachment, adjunto.
