reakcióba

Reakcióba is the illative case form of the Hungarian noun reakció, meaning into or into the state of a reaction. In Hungarian grammar, the illative case marks direction toward or involvement in something, and for reakció the form is reakcióba. It is used with verbs that express entering, joining, or participating in a reaction.

In usage, reakcióba typically appears in contexts where a subject is moving toward or becoming part of a reaction. This can be linguistic, describing participation in a social or rhetorical reaction, or scientific, describing substances being introduced into a chemical reaction. The form is maintained across standard Hungarian syntax and is not a standalone lexical item; its meaning derives from the base word reakció plus the illative suffix -ba.

Examples include sentences like: “A kísérlet során az oldatot reakcióba vezetik be,” which conveys introducing the solution into the reaction, and “A résztvevők reakcióba léptek,” indicating that the participants joined the reaction. The exact nuance depends on the surrounding verb and context, but the core idea is movement toward or involvement in a reaction.

Etymology and relation to other forms: reakcióba is derived from reakció with the illative suffix -ba (harmonized as -ba). Related forms include the nominative reakció (reaction) and other inflected forms used for different cases or verbs. See also reakció and illative case in Hungarian grammar.
