Alternado

Alternado is a term used in Portuguese and Spanish to describe something that alternates or is performed in turns. It derives from the verb alternar and from Latin alternare. In both languages, alternado functions as an adjective and as the past participle used in compound tenses, and it can describe processes, patterns, or states that change in a cyclic fashion.

In practical usage, alternado characterizes patterns, sequences, or arrangements in which two or more options take turns. Examples include horário alternado (alternating schedule), turnos alternados (alternate shifts), and colores en un patrón alternado (colors in an alternating pattern). In biology, folhas alternadas describe leaf arrangement in which leaves occur singly at successive points along a stem, rather than in opposite pairs.

In other domains, the term can appear in descriptions of mechanical systems, workflows, or rules that rely on alternation. Related concepts include alternancia (the process or result of alternating) and alternar (to alternate). The word is common in Latin American Portuguese and Spanish-speaking contexts and is often used to distinguish alternating from other kinds of patterns or arrangements.

Notes and variations: while alternado is widely understood in everyday language, some technical fields may prefer more specific terms (for example, alternancia or alternación in reference to broader phenomena of alternation). The exact usage can vary by country and discipline, but the core meaning—alternating or taking turns—remains consistent.
