liikkeellisiin
Liikkeellisiin is the illative plural form of the Finnish adjective liikkeellinen, meaning movement-related or kinetic. The base liike means movement, and the suffix -ellinen forms an adjective indicating a quality, so liikkeellinen denotes something that has to do with movement. When describing multiple nouns in the illative case (into/onto something), the adjective takes the illative plural ending -iin, producing liikkeellisiin. This form is typically found in phrases where movement-related categories or targets are being specified.
In practice, liikkeellisiin is used before a plural noun in the illative case. For example, kohteet jaettiin
Usage notes: liikkeellisiin is primarily a descriptive or technical term seen in academic, scientific, or analytic
