znanstveno
Znanstveno is a Slavic adjective meaning "scientific" or "scientific-". It is derived from the noun znanost, which refers to knowledge or science, and is cognate with the verb znati, meaning "to know." The root of the term can be traced back to Proto-Slavic *znanstь, signifying knowledge or learnedness, and is related to the Latin word scientia, which in turn comes from the verb scire (to know). The suffix -sko attaches to create an adjective denoting relation or characteristic, so znanstveno literally translates as "pertaining to knowledge" or "relating to science."
In contemporary use, znanstveno is employed across Croatian, Bosnian, Serbian, Slovenian, and other South Slavic languages
The adjective has contributed to the development of numerous related constructions in Slavic languages, including neuter
