älyllistä

älyllistä is the partitive singular form of the Finnish adjective älyllinen, meaning intellectual or rational. It is used to describe abstract mental qualities or activities and is common in formal or semi-formal Finnish, particularly in writing about philosophy, science, or culture. When used predicatively with the verb olla, it often appears as Se on älyllistä (It is intellectual). When modifying a noun, älyllista is used in the partitive case, as in älyllistä pohdintaa (intellectual reflection) or älyllistä keskustelua (intellectual discussion).

Älyllinen versus älykäs: älyllinen refers to intellectual quality in a broader, more formal sense, often associated with reasoning, theory, or critique. Älykäs refers more to cleverness or practical intelligence and is common in everyday language. The adverb form is älyllisesti, meaning “intellectually,” as in älyllisesti pohditussa kysymyksessä (in an intellectually considered question).

Etymology and usage: älyllinen is built from the stem äly, meaning mind or intellect, with the adjectival suffix -llinen. The form älyllistä is a standard partitive form used with non-countable or indefinite nouns and in predicative constructions. The word tends to occur in academic, literary, or analytical styles and is less common in casual spoken Finnish, where other terms such as älykäs or järkevä might be used depending on nuance.
