kopástól

kopástól is a Hungarian postpositional phrase formed from kopás (wear, abrasion) and the postposition -tól, meaning from or away from. It marks the source or cause of wear, and is primarily used in technical, maintenance, and engineering texts to indicate that something is affected by or protected against wear. In everyday language, a more common expression is kopás miatt (due to wear), but kopástól appears when the emphasis is on the source or risk of wear.

In usage, kopástól functions as an adverbial postpositional phrase and typically accompanies a noun or noun phrase to specify the origin of the wear-related effect. It does not form new inflections on its own; rather, it remains a fixed unit within the sentence. The expression can be combined with other postpositional phrases to describe multiple sources of deterioration, for example kopástól és korróziótól (from wear and corrosion).

Examples:

- A csapágyak kopástól védelme érdekében kenést alkalmaznak.

- A felület kopástól védett marad a hosszú használat során.

- A készülék kopástól való védelme kiemelten fontos a karbantartási tervben.

Etymology and register: kopástól combines kopás (wear) with the suffix -tól (from). It is typical of technical language, where precise attribution of a defect or protection to its cause is needed. The phrase contrasts with kopás miatt, which states the cause in a more general way, and with forms such as kopástól való védelme, which emphasize protection from wear.
