Kaksinkertaisissa

Kaksinkertaisissa is a Finnish grammatical form meaning “in twofold” or “in duplicate.” It is the inessive plural form of the adjective kaksinkertainen, which denotes twofoldity, doubling, or multiplicity. The form is used to modify a plural noun in the inessive case, indicating that the described characteristic or entity exists in twofold copies or degrees within the referenced context.

Morphology and usage context: The base kaksinkertainen combines the numeral kaks- (two) with -inkertainen (fold). In Finnish, adjectives agree with the noun they modify in number and case; hence the plural inessive ending -issa/-issä attaches to the stem to yield kaksinkertaisissa. This form appears in formal or technical prose rather than everyday speech.

Typical contexts: Kaksinkertaisissa is common in scientific, mathematical, or descriptive writing when a property is described as doubled or present in two parallel instances. It can describe data, structures, risks, or relationships that occur in twofold form. Example contexts include research reports, technical specifications, and analytical commentary.

Related forms and notes: Related forms include kaksinkertainen (singular nominative) and kaksinkertaiset (plural nominative), along with other inflected variants such as kaksinkertaisiin or kaksinkertaisissa in different grammatical cases and numbers. The term is chiefly used in written Finnish; in ordinary speech speakers may use periphrastic constructions to express the same idea.
