reagido

Reagido is the Portuguese past participle of the verb reagir, meaning having reacted or reacted. It is used as an adjective or participle to describe someone or something that has responded to a stimulus, event, or situation. Common constructions include using the participle in compound tenses, such as "tem reagido," to indicate ongoing or recent reaction.

Etymology and usage context: Reagido derives from the verb reagir, which itself comes from the prefix re- plus agere (to act). In modern Portuguese, reagir means to respond or react, and reagido is the fixed participial form used in perfect tenses and, less frequently, as an adjectival form that agrees with gender and number (reagido / reagida, reagidos / reagidas).

Grammatical notes: The past participle reagido is used with auxiliary ter to form perfect tenses (ele tem reagido bem, ela tem reagido às críticas). When treated as an adjective, the participle can agree in gender and number with the noun it qualifies (reagido, reagida; reagidos, reagidas), though its adjectival use is less common in everyday language than its verbal use in compound tenses.

Examples:

- A empresa tem reagido rapidamente às críticas.

- Os cidadãos reagiram de forma pacífica.

- O público reagiu bem à anúncio.

See also: reagir, reação, reagente (note: reagente is a chemical term meaning reagent).
