mielialansa

Mielialansa is the genitive possessive form of the Finnish noun mieliala, meaning "one's mood" or "state of mind." The third-person possessive suffix -nsa (sometimes written as -nsä) attaches to the noun to indicate that the mood belongs to he, she, or it. The form is commonly used to refer to a person's mood without naming the subject repeatedly, for example in phrases like “Hänen mielialansa muuttui nopeasti” (Her/His mood changed quickly) or “Mielialansa mukaan hän teki päätöksen” (According to her/his mood, she/he made the decision).

In Finnish, mielialansa functions as a noun phrase that can be the subject, object, or part of a larger clause, and it often appears in discussions of daily emotions, behavior, or decision-making. Its usage can convey nuance about how much a person’s mood influenced an action or judgment without attributing the action directly to the person’s character.

Related forms include mielialasi (your mood) and mielialamme (our mood), reflecting the same noun with different possessive suffixes. The plural form mielialojensa would mean “their moods.” Mieliala itself denotes mood in general, while mielialansa specifies possession by a third party. In everyday language, the term is common in both casual conversation and more formal descriptions of affective states, mood fluctuations, and related behavioral observations.
