kokonaislukuineen

Kokonaislukuineen is a Finnish word form composed of the noun kokonaisluku ("integer; whole number") and the comitative suffix -ineen, which conveys accompaniment or association and can be translated as "with" or "together with". The resulting form kokonaislukuineen literally means "with its/their integers" or "together with the integers".

As a morphological construction, -ineen attaches to a nominal base to indicate that the named entity is accompanied by or possesses the thing expressed by the base. The suffix is common in written and spoken Finnish and appears in both formal and neutral registers; it often produces compact expressions where English would use a phrase such as "together with" or "including". Example: Ryhmä tutkijoita esitteli mallin kokonaislukuineen ja murtolukuineen (The research group presented the model along with its integers and fractions).

Kokonaisluku itself derives from kokonainen ("whole") + luku ("number"). Usage of the combined form follows Finnish phonological and morphological rules, and it is not a separate lexical entry but an inflected or suffixed phrase-like unit. Related comitative formations include ystävineen ("with his/her friends") and laitteineen ("with its devices"). The form is productive and can be applied to many nouns to express accompaniment, inclusion, or association.
