Ionoitujen

Ionoitujen is a Finnish inflected form derived from the verb ionoida (to ionize) or from the related noun ionointi (ionization). In technical and scientific Finnish, it is used to describe items that have undergone ionization and functions as a modifier in noun phrases. The form often appears when talking about groups of samples, particles, or substances that are ionized, such as ionoitujen näytteiden koostumus or ionoitujen hiukkasten käyttäytyminen.

Grammatical notes: Ionoitujen is typically understood as the genitive plural form associated with an adjective or past participle meaning “ionized.” It is used to link to a head noun in a possessive or descriptive sense, for example in phrases like ionoitujen näytteiden analyysi (“analysis of the ionized samples”). In everyday language the form is less common, and it is most frequent in formal or technical texts, where precise description of ionization status is important.

Usage examples: After the ionization process, ionoitujen näytteiden sähkönjohtavuus kasvoi. The study compares ionoitujen ja ei-ionoitujen aineiden kemiallisia ominaisuuksia (the chemical properties of ionized and non-ionized substances). These examples illustrate how ionoitujen can signal a specific state of ionization affecting the noun it modifies.

Etymology and morphology: The form reflects Finnish derivational patterns from ionoida/ionointi, using a participial adjective stem and the genitive plural ending. Exact inflection can vary with context and dialect, so consulting standard Finnish grammar is advisable for precise usage in complex phrases.
