laatullinen

Laatullinen is a Finnish adjective formed from the noun laatu (quality) with the adjectival suffix -llinen, used to signify that something has or relates to quality. In normative Finnish, the usual form is laadullinen (quality-related, qualitative). Laatullinen is considered nonstandard or rare and is typically encountered as a spelling variant, a typographical error, or in creative or dialectal contexts. Some writers may use laatullinen for stylistic reasons or to emphasize a particular notion of quality outside standard orthography. Because of its rarity and potential confusion with laadullinen, its appearance in formal texts is discouraged.

Etymology: derives from laatu + -llinen. The suffix -llinen indicates possession of a quality or characteristic.

Usage: mostly found in informal writing, marketing slogans, or dialectal speech. In most written Finnish, laadullinen should be preferred when meaning "quality-related" or "of quality." If used in compound terms or product labeling, the intended meaning should be clarified to avoid misinterpretation.

Alternatives: laadullinen; laadun- based phrases such as laadulliset ominaisuudet.
