Kokonaissummaan

Kokonaissummaan is a Finnish word form derived from kokonaissumma, literally "total sum" or "overall amount." In Finnish grammar kokonaissummaan is the illative singular form, used to indicate motion toward or addition into the total amount (roughly "into the total sum" or "to the total amount"). The base components are kokonais- (whole, entire) and summa (sum, amount).

The term appears commonly in contexts where quantities are aggregated or adjusted, such as accounting, budgeting, statistics and legal or administrative documents. It is used when describing operations that change or are applied to an overall total: for example, adding an item to an accumulated total or allocating funds into a consolidated sum. In everyday Finnish it can occur in spoken and written instructions, financial reports and technical descriptions.

Etymologically the form reflects regular Finnish case marking: the illative case expresses direction toward or entry into something. Comparable cases are used across Finnish to mark similar relationships for other nouns. Examples of usage include phrases that translate as "add this to the total" or "the adjustment is included in the total amount." The term is grammatical rather than lexical in the sense that it represents a specific case form of a common compound noun.
