aéreo

Aéreo is an adjective used in Spanish and Portuguese to describe things related to air or to flight. It denotes anything airborne or associated with aviation and airspace, and it agrees in gender with the noun it modifies (aéreo/aérea in both languages). The term is common in technical, logistical and geographical contexts, with phrases such as transporte aéreo (air transport), imagen aérea or fotografía aérea (aerial image or photograph), ruta aérea (air route), and navegación aérea (air navigation). In Portuguese, additional examples include reconhecimento aéreo (aerial reconnaissance) and atividade aérea (air activity).

Etymology and usage notes: Aéreo derives from the aero- root, linked to the Greek aēr- meaning air, and has been integrated into the Romance languages with the characteristic acute accent on the e. It is closely related to the English word aerial and to the broader concept of air-based or aviation-related activities. In everyday language, the term appears mainly in technical, scientific, and industry contexts rather than in casual speech.
