supresor

Supresor is the Spanish-language term for suppressor and is used in several disciplines to denote an agent, device, or process that reduces or opposes a signal, effect, or outcome.

In firearms, a suppressor (supresor) is a device attached to the muzzle to reduce muzzle blast and visible flash. It slows and directs expanding gases to lower noise and recoil; it does not render a gun truly silent, particularly with supersonic ammunition. Effectiveness depends on the design (internal baffling) and ammunition, and legal status varies by jurisdiction, with many places regulating ownership and use.

In electronics, a surge suppressor (surge protector) is a device that limits voltage transients to protect equipment. Common types include metal-oxide varistors (MOVs), gas discharge tubes, and transient-voltage suppression diodes. They are widely used in power strips, consumer electronics, and industrial power systems.

In biology and medicine, the term often corresponds to tumor suppressor genes, which encode proteins that regulate cell growth and DNA repair to prevent cancer. In immunology, suppressor T cells, an older term for regulatory T cells, help maintain immune tolerance and limit immune responses.
