Reaktivno

Reaktivno is a neutral term used in several South Slavic languages, including Croatian, Serbian, Bosnian, and Slovenian. It is the neuter singular and adverbial form of the adjective reaktivan/reaktivna, depending on gender and noun. The word is common in technical, scientific, and formal writing to indicate that something involves a reaction or responds to stimuli.

In chemistry and materials science, reaktivno describes substances with a tendency to participate in chemical reactions. A reaktivno sredstvo is a reactive agent; high reaktivnost (reactivity) implies rapid reaction or energy release. The term also appears in contexts such as reaktivno ponašanje materijala, meaning reactive behavior under certain conditions. The concept is closely related to nouns like reaktivnost or reaktivno ponašanje.

In computing and information technology, the term is used to translate “reactive” in phrases such as reactive programming (reaktivno programiranje) or reactive systems, referring to software that responds to events, data changes, or user input in a time-ordered, asynchronous manner.

Etymology and usage notes: Reaktivno derives from the noun “reakcija” and common Slavic morphological patterns for forming adjectives and adverbs; it mirrors the international scientific term “reactive” and is widely used in technical vocabularies across Slovenian, Croatian, Serbian, and Bosnian contexts to denote responsiveness or chemical reactivity.
