luotettamattomasta

Luotettamattomasta is a Finnish inflected form of the adjective luotettamaton, meaning unreliable or untrustworthy. The form is used when the adjective modifies a noun in a particular grammatical case, most commonly the elative case, to indicate origin or source. In practice, luotettamattomasta typically appears as part of a noun phrase such as luotettamattomasta lähteestä, meaning from an unreliable source.

Grammatically, luotettamaton is the base form meaning unreliable. It combines with Finnish inflection patterns to produce various case forms, including luotettamattomasta, luotettamattomasta lähteestä or luotettamattomasta henkilöstöstä, depending on what is being described. The word can be used in attributive position before a noun or, in certain constructions, with a noun to express that the described item or source is unreliable. The comparative and superlative forms follow the regular pattern for adjectives: luotettamattomampi (more unreliable) and luotettamattomin (most unreliable).

Usage and nuance: luotettamattomasta emphasizes unreliability in relation to a specific context, such as a source, information, or claim. It is common in journalism, academic writing, and everyday language when evaluating evidence, statements, or data. While luotettamaton and luotettavampi convey related ideas, luotettamattomasta provides a precise, source-focused nuance by indicating origin from unreliability rather than simply describing the item as unreliable.

Related forms include luotettavuus (reliability) and luotettamattomuus (unreliability or unreliability as a concept). See also luotettava (reliable) for contrast. In usage, care should be taken to ensure the correct case endings align with the noun being described.
