ulkoisista

Ulkoisista is a Finnish inflected form derived from the adjective ulkoinen, meaning external or foreign. It is used to describe origin, influence, or sources that come from outside a person, group, system, or context. In practice, ulkoisista appears in phrases that indicate externality, such as ulkoisista lähteistä (from external sources) or ulkoisista tekijöistä (from external factors). The form serves to mark that the referenced noun is in a relationship with something outside the subject.

Grammatically, ulkoisista is the elative plural form that accompanies a plural noun in the same case. Finnish adjectives agree with the nouns they modify in number and case, so ulkoisista will appear whenever the corresponding noun is in the elative plural. Because it signals exteriority rather than type, the term is common in scientific, policy, media, and academic writing, where distinctions between internal and external factors or sources are important.

Etymology and related forms: ulkoinen is the base adjective meaning external or foreign, from which various inflected forms are derived through Finnish word-formation and case endings. The segment -is-ta is part of the inflection that marks elative plural and agreement with the following plural noun.

Usage notes: ulkoisista conveys a neutral to descriptive sense of external origin. It should be distinguished from terms referring to internal aspects or from more specific labels for foreign things. As with many Finnish inflections, clarity comes from ensuring the modifier and noun align in case and number.
