täysi

Täysi is a Finnish adjective meaning "full" or "complete." It denotes that something reaches its maximum capacity or extent and is commonly used with nouns to express fullness, for example täysi lasi (a full glass) or täysi kuorma (a full load). The term can describe both tangible quantities and more abstract dimensions, such as täysi valmius (full readiness) or täysi ymmärrys (complete understanding).

In everyday language, täysi appears in a variety of expressions and compounds. A well-known and productive form is täysi-ikäinen, meaning someone who is legally an adult. The word is derived from the Finnish root täy-, which conveys fullness, and it has cognates in related Finnic languages, such as Estonian täis.

Grammatically, täysi behaves as a regular attributive adjective, agreeing with the noun it modifies in number and case.

In translation, täysi is typically rendered as "full" or "complete," depending on context. It is distinct from synonyms such as täydellinen, which carries an additional nuance of perfection. Täysi is a common word in common speech, journalism, and formal language, used to describe anything from physical quantity to abstract states of wholeness.
