Teorinis

Teorinis is an adjective used in Lithuanian to denote something related to theory rather than to practice. It describes ideas, models, frameworks, or approaches that are abstract, principle-based, or explanatory in nature. The term is widely applied across disciplines such as science, humanities, and social sciences to distinguish the theoretical component from practical or applied aspects.

Etymology and form: The word derives from teorija (theory) with the suffix -inis, forming an adjective that agrees with masculine nouns. The root theory itself ultimately traces to the Greek theoria. In use, teorinis typically partners with a noun to specify the theoretical character of that noun, for example teorinė fizika (theoretical physics) or teoriniai modeliai (theoretical models).

Usage and examples: Common phrases include teorinis darbas (theoretical work), teorinis požiūris (theoretical perspective), and teorinė ekonomika (theoretical economics). In education and research, the term helps distinguish theoretical investigations from practical or applied work, such as taikomoji (applied) or praktinis darbas.

Context and scope: The concept of teoriškumo appears in many fields, including mathematics, physics, economics, philosophy, and the social sciences. In these contexts, teorinis work focuses on developing and refining concepts, hypotheses, and models that explain phenomena, whereas practical work emphasizes implementation, testing, or application of those ideas.
