äänitteiseen

äänitteiseen is a Finnish inflected form that can be traced to the noun äänite, meaning a sound or audio recording, and the related adjective äänitteinen, meaning recording-related or pertaining to a recording. The form represents an illative-like function for the adjective stem, indicating movement toward or relation to something described as recording-related. In practice, äänitteiseen is most often encountered in more formal or technical language rather than everyday speech.

Grammatically, äänitteinen is an adjective formed with the typical -inen suffix in Finnish. When inflected for case and number, the illative singular form commonly appears as -iseen in adjectives ending in -inen, giving äänitteiseen as a plausible illative form meaning “to a recording-related [item]” or “into a recording-related material.” The standard illative of the noun äänite, however, is äänetteeseen, and the plural illative of the noun is äänitteisiin. Thus, äänitteiseen is distinct and reserved for contexts where the adjective is being inflected rather than the noun.

Usage and context, äänitteiseen tends to appear in academic, archival, or media- studies language, where material is described as related to recordings. It is relatively rare in everyday Finnish, and many speakers would prefer phrases such as äänitteeseen liittyvä or äänitteellisiin aineistoihin to express relatedness without relying on the specific illative form.
