älyynsä

älyynsä is a Finnish grammatical form derived from the noun äly, meaning mind or intellect. It combines the illative case suffix -yn with the third-person possessive suffix -nsä, producing the meaning “into his/her mind” or “to his/her mind.” The construction signals a mental event or direction toward the mind of the person indicated by the possessive suffix.

Usage notes:

The form is used to describe thoughts, ideas, or insights entering or existing in a particular person’s mind. It is commonly found in literary and formal prose, and can appear with verbs of coming to mind, such as tulla (to come), or other mental processes. It highlights ownership of the mental event and specifies whose mind is involved, which distinguishes it from more general phrases like äly or älyä without possessive marking.

Examples:

- Uusi idea tuli hänen älyynsä. (A new idea came into his mind.)

- Oivallus tuli hänen älyynsä keskustelun aikana. (An insight came into his mind during the discussion.)

Etymology and related forms:

The base is äly (mind). The illative suffix -yn marks direction toward a destination, while the possessive suffix -nsä encodes third-person ownership. The form is one word and is distinct from other possessive constructions in Finnish.
