keskiarvonsa

Keskiarvonsa is a Finnish possessive phrase meaning “his/her/its average.” It combines the noun keskiarvo, meaning average or arithmetic mean, with the third-person singular possessive suffix -nsa, indicating that the average belongs to someone or something. The form keskiarvonsa indicates that the possessor is a third person singular subject.

In Finnish, the possessive suffix appears as -nsa or -nsä depending on vowel harmony. Because keskiarvo ends with a back vowel, the suffix takes the form -nsa in keskiarvonsa rather than -nsä. This suffix attaches to the stem to create a noun phrase that functions like a standalone noun in a clause.

Keskiarvonsa is used in contexts where a specific individual’s average needs to be stated or discussed, such as academic performance, sports statistics, or data reporting. It denotes ownership of the average by a named person or entity and can occupy typical grammatical roles such as subject, object, or complement within a sentence.

Examples include: “Hänen keskiarvonsa on 3,8.” (“His/Her average is 3.8.”) and “Oppilaan keskiarvonsa on parantunut viime lukuvuonna.” (“The student’s average has improved over the past school year.”)
