Katódtól

Katódtól is a Hungarian postpositional form derived from the noun katód (cathode) together with the suffix -tól, which marks origin or source. In usage, katódtól means “from the cathode” and is employed to describe location, direction, or sourcing of electrical or electrochemical phenomena. It appears in scientific writing, technical descriptions, and instructional texts dealing with circuits, cells, tubes, and related equipment.

Etymology and form: katód is a loanword of Greek origin, commonly traced through German Kathode or French cathode. The postpositional suffix -tól is a standard Hungarian marker for origin, yielding katódtól as a single word that conforms to Hungarian orthography and phonology. The combination reflects regular noun-to-postposition derivation without semantic shift beyond indicating source.

Usage and examples: In practice, katódtól is used to specify that something originates at or comes from the cathode. For example, one might refer to “a katódtól érkező áram” (the current coming from the cathode) or describe measurements as “katódtól mért potenciálkülönbség.” It can also appear in comparative or descriptive phrases such as “katódtól függő elektromos jel” to indicate a relation to the cathode. In broader contexts, the term helps distinguish components or signals associated with the cathode from those associated with other electrodes, such as the anódtól.

See also: katód, anód, katódikus (adj.), elektroncsövek és galvanikai sejtek.

Notes: katódtól functions as a specific, technical prepositional form and is not a standalone noun beyond its role in phrases describing origin relative to the cathode.
