älyyn

älyyn is the illative singular form of the Finnish noun äly, meaning intelligence, wit, or intellect. In Finnish grammar, the illative case marks direction or destination, often translated as “into” or “toward.” Therefore älyyn conveys “into the mind” or “into the intellect,” referring to movement toward mental processing or understanding. The term appears primarily in formal or literary contexts; in everyday speech speakers more commonly discuss cognitive processes using other constructions such as mieleen or ajatuksiin.

The stem äly belongs to words connected with mind and cognition; its derivatives include älykäs (intelligent), älykkyys (intelligence, cleverness), and älyllinen (intellectual). The illative suffix -yn attaches to the stem, yielding älyyn. As with other illative forms, it can occur with possessive suffixes in phrases, for example älyynsä (“into his/her intellect”).

Usage notes: the illative form is productive for abstract nouns but is relatively uncommon in casual conversation; its use is more frequent in literature, academic writing, or rhetorical expressions. The form does not denote a separate concept beyond its function as a grammatical case of äly.
