teiginiais

Teiginiais is the instrumental plural form of teiginys, a Lithuanian term meaning a statement or proposition. In everyday usage, teiginiai refer to sentences or claims that express information, assertions, or beliefs that can be true or false. In philosophy and logic, teiginiai are the primary bearers of truth values and can be atomic (simple) or complex, formed through logical connectives such as and, or, and not. The study of teiginiai concerns their logical form, how they combine, and how conclusions follow from them.

In formal contexts, teiginiai are analyzed for coherence, consistency, and deductive validity. A set of teiginiai can be used to test arguments, evaluate evidence, and construct proofs. The terminology emphasizes content over grammatical structure, focusing on what is claimed rather than how it is said. This makes teiginiai a central concept in disciplines ranging from logic and mathematics to rhetoric and epistemology.

The instrumental form teiginiais appears in sentences where multiple statements are referenced or relied upon, often after prepositions or verbs that govern instrumental case. Example: Remiantis teiginiais, tyrimas išvadą padarė teigiamą. This usage demonstrates how Lithuanian morphology marks relationships between statements and the actions or judgments based on them.
