reintroducir

Reintroducir is a Spanish verb meaning to introduce again or to reintroduce something that had been removed or is no longer present. It is commonly used for ideas, practices, policies, technologies, and, importantly, for ecological contexts where a species is returned to a former habitat after local disappearance or extinction in that area.

Etymology and morphology: The verb combines the prefix re- with introducir (to introduce). It derives from Latin re- and introducere (to lead in). In the present tense, it follows the pattern of -cir verbs: yo reintroduzco; tú reintroduces; él, ella, usted reintroduce; nosotros reintroducimos; vosotros reintroducís; ellos, ellas, ustedes reintroducen. The pretérito simple is reintroduje, reintrodujiste, reintrodujo, reintrodujimos, reintrodujisteis, reintrodujeron. The past participle is reintroducido and the gerund is reintroduciendo.

Common uses: In ecology and conservation, reintroducir describes returning a species to part of its historical range after extirpation, such as reintroducir el lobo ibérico in suitable habitats. In policy, governance, and organizational contexts, it can refer to reintroducing a law, regulation, program, or practice that had been suspended, modified, or set aside. In everyday language, it may denote reintroducing an idea, technology, or cultural practice into current use.

Nuances: Successful reintroducción depends on habitat suitability, genetic diversity, and ongoing management; it differs from introducing non-native species, which can carry ecological risks. The noun form is reintroducción.
