ilmentymillä

Ilmentymillä is a Finnish word form, the adessive plural of the noun ilmentymä. As a case form it conveys meanings related to location, accompaniment or instrumentality, commonly translated into English as "on/at/with the manifestations" or "in terms of manifestations" depending on context.

The base noun ilmentymä comes from the verb ilmentyä ("to manifest, to appear") with the nominalizing suffix -mä, and denotes an instance, manifestation, or expression of a phenomenon. In Finnish morphology the adessive plural ending -illä marks presence or association at multiple instances: ilmentymillä thus refers to several manifestations regarded as sites, contexts, or means.

Ilmentymillä appears in a range of registers. In scientific and medical texts it can refer to observable manifestations of a condition (e.g., "taudin ilmentymillä" – "with the disease's manifestations"); in cultural or literary analysis it may denote different expressions of a theme; in general language it can indicate being among or associated with particular instances. The precise nuance depends on verbs and modifiers used with the form.

Related forms include the nominative ilmentymät (manifestations), the singular adessive ilmentymällä, and other case forms such as ilmentymässä (inessive) and ilmentymien (genitive plural). Understanding ilmentymillä requires attention to Finnish case functions and the semantic role assigned by the adessive in context.
