dimensioissa

Dimensioissa is a Finnish inflected form meaning "in the dimensions" or "within dimensions". It is the inessive plural of the noun dimensio, a loanword corresponding to the English "dimension". Morphologically, it combines the stem dimensio- with the inessive plural ending -issa, which denotes location or state inside multiple items.

As a grammatical form, dimensioissa appears in contexts that discuss spatial, conceptual or abstract dimensions. In science and mathematics, it is used when referring to properties or phenomena that occur within multiple dimensions, for example in physics (extra spatial dimensions) or in multivariable analysis. In computing and data science, dimensioissa can describe structures or operations that operate across several dimensions, such as arrays, tensors or multidimensional datasets. In literature and popular culture, the term is frequently employed in speculative fiction to denote events occurring within alternate or parallel dimensions.

Examples in Finnish include: "Tämän ilmiön käyttäytyminen eri dimensioissa on monimutkaista" (The behavior of this phenomenon in different dimensions is complex) and "Tarina liikkuu useissa eri dimensioissa" (The story moves through several different dimensions).

As an inflected form rather than a lemma, dimensioissa is typically listed under the dictionary headword dimensio and is part of the wider system of Finnish locative cases used to express spatial and metaphorical location.
