Megkezdésekor

Megkezdésekor is a Hungarian temporal expression used to indicate the moment when something begins. It translates roughly to “at the start” or “upon beginning.” The form is formed from the nominalized act of beginning (megkezdés / megkezdése) plus the time suffix -kor, producing a fixed phrase that functions as an adverbial time element.

In grammar terms, megkezdésekor behaves as a non-finite, nominal adverbial unit that introduces a time reference for the main clause. It does not mark person or number and is typically used in formal or technical writing. The expression is more precise and formal than everyday alternatives such as a kezdéskor or indításkor.

Usage is common in manuals, regulations, project plans, safety protocols, and academic prose. It sets out a condition or a precondition tied to the initiation moment. Depending on the desired style, it can be substituted with more common expressions without changing the core meaning, for example a kezdéskor or az indításkor, though such substitutions may alter tone.

Examples:

Megkezdésekor ellenőrizze a készülékek állapotát és a biztonsági rendszereket.

A projekt megkezdésekor pontos ütemtervet kell kidolgozni.

Megkezdésekor szükséges a megfelelő védőfelszerelés.

Notes: The related noun megkezdés refers to “the act of starting,” while megkezdésekor specifies the timing. The term is widely understood in formal Hungarian and is often preferred in technical documentation.
