molekijska

Molekijska is an adjective used in several South Slavic languages, notably Croatian, Bosnian, and Serbian, to mean molecular and to describe phenomena at the scale of molecules. It is the feminine singular form of the adjective that derives from the noun molekula. Adjectives in these languages agree with the gender and number of the nouns they modify, giving rise to related forms such as molekijski (masc), molekijsko (neuter), and molekijske (plural).

In linguistic terms, molekijska denotes attributes or qualities belonging to or relating to molecules. In scientific writing in these languages, more general or standardized terms like molekularna are often used for widespread concepts such as molecular biology or molecular chemistry, but molekijska can appear in phrases where the feminine noun governs the agreement, or in particular stylistic or historical contexts.

Etymologically, molekijska traces to the root molekula, meaning molecule, which in turn derives from the Greek word molekule and the Latin molecular from the root moles, meaning a mass. The form molekijska therefore embeds the root meaning of “of a molecule” within the typical Slavic adjectival ending for feminine singular.

Usage notes: molekijska functions as a grammatical form rather than a standalone technical term in English-language contexts. It is primarily encountered in texts written in Croatian, Bosnian, or Serbian, and its applicability or exact form can vary with dialect and standard usage. When translating or writing for broader audiences, speakers often substitute the more universally recognized term molekularna or closely related equivalents.
