Taattu

Taattu is a Finnish adjective meaning guaranteed, assured, or certain. It is commonly used in everyday language, marketing, and consumer contexts to indicate that a claim, service, or product comes with a promise of reliability or a warranty.

The word is formed from the verb taata, meaning to guarantee, with the adjectival suffix -ttu. In standard Finnish, taattu can function both attributively and predicatively: for example, taattu laatu (guaranteed quality) and Tuote on taattu kestäväksi (The product is guaranteed to be durable). Its use emphasizes assuredness rather than absolute certainty, and the exact implication can vary with context, especially in marketing or contractual settings.

In practical terms, taattu appears in phrases that convey assurances about delivery, quality, safety, or performance. It is often paired with nouns related to guarantees, such as laatu, toimitus, or kesto, to reinforce the message of reliability. While taattu is widely understood, it is not a formal legal term in itself; more formal or technical contexts might rely on takuu (warranty) or other explicit guarantees.

Related terms include takuu (warranty), taata (to guarantee), and the broader category of adjectives formed from verbs by the -ttu suffix. Taattu remains a common, neutral descriptor in Finnish, suitable for consumer-facing language as well as general statements about reliability.
