muotoisuuden

Muotoisuuden is a Finnish inflected form, the genitive singular of the noun muotoisuus. Muotoisuus is built from muoto ("form, shape") and the abstracting suffix -isuus, and denotes the quality or state of having form, formal properties, or formality in a general sense. As muotoisuuden, the word is used to indicate possession, description, or relationships that require the genitive case in Finnish.

In grammar, the genitive singular ending -n marks ownership or a dependent relation (for example, "muotoisuuden merkitys" — "the significance of formality/form"). Muotoisuuden can appear in noun phrases, attributive constructions and certain verbal complements where the genitive is required. The word is part of standard Finnish vocabulary and follows regular declension patterns for long-stem abstract nouns.

In aesthetic, philosophical and design contexts, muotoisuus refers to formal characteristics of objects, compositions or structures — the way elements are arranged, their shape and formal coherence. It is used in discussions of visual arts, architecture, literary form and design theory to distinguish formal qualities from content, function or materiality.

Related terms include muoto (form), muotoilla (to shape), muotoilevuus (shapeliness) and muotoiltu (shaped). Usage depends on context: in everyday language it may emphasize appearance or form, while in specialist discourse it carries technical or theoretical meaning.
