Reducen is the third-person plural present indicative form of the Spanish verb reducir. It is used with subjects such as ellos, ellas, or ustedes in standard Spanish to mean "they reduce" or "you all reduce." The form appears in a wide range of registers, from everyday speech to formal writing.

Origin and morphology: Reducir comes from Latin reducere, meaning to bring back or to restore. In modern Spanish, reducir follows the irregular -cir verb pattern with a stem change in the first person singular (yo reduzco); the other present forms are reduces, reduce, reducimos, reducís, reducen.

Usage: In everyday Spanish, reducen expresses action of decreasing or lowering quantities, rates, or levels. In technical contexts, it commonly pairs with nouns like emisiones, consumo, costos, or temperaturas. Example: "Las emisiones de CO2 se reducen con estas políticas" or "Ellos reducen la velocidad del vehículo para conservar combustible."
