Täiesti

täiesti is an Estonian adverb meaning "completely", "totally", or "entirely". It functions as an intensifier to indicate that an action, state, or quality is complete or absolute, as in täiesti õige ("completely correct") or see on täiesti võimalik ("that is entirely possible").

Etymology traces täiesti to the adjective täielik ("complete") and ultimately to the Finno-Ugric root related to Estonian täis and Finnish täysi, which denote fullness. The adverbial suffix -sti is a common means in Estonian to form adverbs from adjectives or stems.

Phonetically, täiesti is typically pronounced with primary stress on the first syllable. Grammatically it is indeclinable and does not take comparative or superlative inflection; intensity is usually expressed by context or by combining it with other modifiers.

In usage, täiesti appears across registers from formal writing to colloquial speech, where it often serves as a pragmatic marker to strengthen assertions or express surprise. It has synonyms such as täielikult and päris in some contexts, and antonyms like osaliselt ("partially") when contrast is needed.

Examples:

- Ta oli täiesti väsinud. (He/she was completely tired.)

- See ei ole täiesti õige. (That is not entirely correct.)

As a frequent and versatile adverb, täiesti is a core element of everyday Estonian expression for conveying completeness or intensity.
