loogilisest

Loogilisest is an Estonian grammatical form derived from the adjective loogiline, meaning logical. It is used in inflected phrases to express relation to logic, such as possession, source, or association, within sentences that discuss reasoning, proofs, or theoretical frameworks. The form is most common in formal or academic Estonian, including philosophy, mathematics, computer science, and linguistic analysis. In everyday language, other inflected forms of loogiline are more frequent, while loogilisest appears in more specialized constructions. The standard adverb meaning “logically” is loogiliselt; loogilisest should not be read as the adverb, though both share the same root.

In terms of etymology, loogiline comes from loogika (logic). The form loogilisest is produced by applying Estonian adjective inflection rules to indicate a relationship with logic in a case that supports attributes such as origin, basis, or attribution to logic. The usage overlaps with fixed expressions and technical terminology where logic governs the discussed content. Related terms include loogika (logic) and loogiline (logical).
