yhteenlaskuna

Yhteenlaskuna is the essive form of the Finnish noun yhteenlasku, meaning an addition or sum. In Finnish grammar, the essive case (ending -na/-nä) expresses a temporary state or role, so yhteenlaskuna translates roughly to “as a sum” or “in the sense of addition.” The term is used in mathematical and didactic language to indicate that something is to be understood or presented as the result of adding numbers.

Morphology and scope: The word is formed from the noun yhteenlasku (the operation or result of adding) plus the essive suffix -na, yielding yhteenlaskuna. It appears mainly in technical or explanatory contexts, where wording needs to emphasize that an expression is an additive sum rather than a product or other operation.

Usage: Yhteenlaskuna is commonly found in mathematical explanations, textbooks, and educational discourse. It signals that a given expression or result should be read as the sum of terms. For example, 3 + 4 yhteenlaskuna on 7, illustrating that the expression is to be evaluated by addition. It can also appear in broader statistical or comparative writing to denote a sum total derived by addition.

Related terms: yhteenlasku (sum, addition), summa (sum), plusmic terms like laskutoimitus (calculation) or summa (sum). The essive form yhteenlaskuna is one of several Finnish grammatical tools used to specify the role or interpretation of a mathematical expression within a sentence.
