teoreetilisest

Teoreetilisest is the elative singular form of the Estonian adjective teoreetiline, meaning theoretical. In Estonian, adjectives agree with the noun they modify in number and case, and teoreetilisest functions as the form that indicates origin or basis in a theoretical sense. It is commonly used to express perspective or grounding in theory, as in phrases such as teoreetilisest vaatepunktist or teoreetilisest lähtekohast.

Etymology and form: teoreetiline derives from teooria, meaning theory, with the productive adjective suffix -iline. The elative singular form teoreetilisest is formed by adding the elative ending to the adjective stem, producing a form that means “from a theoretical [point of view/ basis].” This form is typically used with nouns in the elative case, where the phrase conveys source or basis.

Usage: teoreetilisest appears primarily in academic, analytical, and formal writing to indicate that something is viewed or grounded in theory rather than empirical observation. It often collocates with nouns such as vaatepunkt, mõiste, lähenemine, or mudel. For example, a sentence might read: “Artikkel käsitleb teemat teoreetilisest vaatepunktist,” meaning that the topic is considered from a theoretical perspective. Another example: “Teoreetilisest mõistest lähtuvad järeldused võivad erineda praktilistest.”
