Poranterissä

Poranterissä is a Finnish word-formation that functions as the inessive plural form of the noun poranteri, meaning drill bit. In Finnish, poranteri denotes a cutting tool used to drill holes, typically part of a set of drill bits. The inessive plural poranterissä translates as “in drill bits” and is used to describe location inside multiple drill bits or features contained within a group of such tools. It appears mainly in technical writing, catalogs, or discussions about Finnish morphology rather than in everyday narrative prose.

Poranteri is a compound noun formed from pora, meaning “drill,” and terä, meaning “blade.” The word follows standard Finnish noun inflection: plural nominative is poranterit, while the inessive plural takes the suffix -issä, yielding poranterissä. The form serves as an example of how Finnish marks location with case endings on concrete objects in technical vocabularies.

Because poranterissä is a grammatical form rather than a proper noun, it does not name a place or organization. It is primarily of interest in studies of Finnish grammar, lexicography, and the way technical vocabulary adapts to inflection.
