erikokoisiin

Erikokoisiin is a Finnish grammatical form rather than a standalone word. It is the plural illative form of the adjective erikokoinen, which means “of different sizes” or “varying in size.” As a case-inflected form, erikokoisiin is used with plural nouns in the illative case to express movement toward or inclusion in categories involving multiple sizes, such as packages or containers.

In practice, erikokoisiin is common in contexts like packaging, inventory, and product catalogs. Typical phrases include erikokoisiin pakkauksiin (into packages of different sizes) or erikokoisiin laatikoihin (into boxes of different sizes). The form signals that the referenced items are available in several sizes and that something is being directed toward that set, rather than to a single size.

Linguistic notes: erikokoinen derives from eri (different) + koko (size) with the suffix -inen to form an adjective. The plural illative ending attached to the adjective appears as -isiin in many contexts (e.g., erikokoisiin). This is a normal part of Finnish inflection and should be understood as a grammatical form rather than a separate lexeme. For comparison, singular forms include erikokoiseen (illative singular) and plural genitive erikokoisten, illustrating how the same root changes with case and number.
