relével

Relével is the instrumental singular form of the Hungarian noun relé, meaning a relay—the electrically operated switch or signaling device used to control circuits. In Hungarian, the instrumental suffix -vel marks the means or instrument by which something is done; relé thus becomes relével, meaning “with a relay” or “by means of a relay.” The noun relé is borrowed from English relay, likely via French relai, reflecting its technical origin.

Usage of relével occurs mainly in technical description, manuals, and schematics, where it specifies that a function is performed using a relay. Examples include phrases like “A relével működtetett kapcsoló gyorsan reagál” (The relay-operated switch responds quickly) and “Az áramkör relével vezérelhető” (The circuit can be controlled by a relay). The form helps distinguish the method from other means of operation, such as mechanical or solid-state switching.

Etymology and morphology: relé, a loanword for relay, gains the instrumental suffix -vel to form relével when indicating means. This pattern is common in Hungarian for instruments or tools used to perform an action.
