Intervencióval

Intervencióval is the instrumental form of the Hungarian noun intervenció, meaning intervention. It denotes the means, instrument, or method by which an action is performed and is roughly equivalent to the English expression “with intervention.” The form is created by attaching the suffix -val/-vel to intervenció, in accordance with vowel harmony, yielding intervencióval.

In use, intervencióval typically appears with verbs that describe actions carried out through an intervention. It is common across domains such as medicine, psychology, education, and public policy, wherever an intervention (medical treatment, program, or policy measure) is central to the described process. It is not domain-specific and describes the manner in which something is achieved via intervention.

Examples:

- A betegséget intervencióval kezelik.

- A beavatkozási programot intervencióval indították meg.

- A kutatást intervencióval tervezték.

Note that intervencióval can be contrasted with intervencióként, which marks the intervention as the role or function in a clause rather than the means.

Etymology and related terms: intervencióval is derived from intervenció, which in turn comes from Latin interventio. Related terms include beavatkozás (intervention), beavatkozik (to intervene), and interventional studies in research contexts.
