Radikaaneilla

Radikaaneilla is a Finnish grammatical form—the adessive plural of the noun radikaani. Radikaani refers in Finnish to a radical or a radical-related expression; in mathematics it denotes the radicand, the quantity under a radical sign, and in chemistry it can refer to a radical species or a related concept in a compound. The form radikaaneilla appears when the sentence discusses several such radicals or when the sense is instrumental or locational ("with the radicals," "on the radicals") according to Finnish case grammar. Because Finnish uses the same base word for different scientific senses, the exact meaning of radikaaneilla depends on context: mathematical texts will interpret it as referring to multiple radikaani under a root, while chemical texts will relate to several radical species.

Etymology and inflection: radikaani is a word adapted to Finnish morphology, a loanword from international scientific vocabulary. The plural nominative is radikaanit; the adessive plural is radikaaneilla, used with appropriate surrounding words to indicate the relationship to multiple radicals. The term is primarily found in technical or didactic Finnish rather than everyday language.

In practice, readers encountering radikaaneilla should rely on the surrounding syntax and any explicit qualifiers (such as matematiikka or kemia) to interpret the precise meaning. The term is part of a broader set of Finnish terms that align with international nomenclature for radicals and radical expressions.
