IDEiden

Ideiden is the genitive plural form of the Finnish noun idea. It is used to indicate possession or relation to multiple ideas and appears in noun phrases such as ideiden määrä (the number of ideas) and ideiden kirjo (the range of ideas).

Origins and form: The Finnish word idea is a loanword, historically from Swedish idé and ultimately from French idée, with roots in Latin or Greek. In Finnish, many -a/-ä nouns form the genitive plural with -iden, yielding ideiden as the genitive plural of ideat. The singular forms include idean (genitive singular) and idea (nominative).

Usage and nuance: Ideiden primarily appears in formal or written language to describe relations among multiple ideas. It marks a plural relationship rather than a change in core meaning and is common in contexts such as education, research, design, and policy discussions. It is used to attribute or relate concepts to more than one idea, for example in analysis of outcomes, or to discuss the scope of ideas under consideration.

Examples: Ideiden määrä kasvoi projektin aikana. (The number of ideas increased during the project.) Ideiden kirjo tarjoaa laajan valikoiman ratkaisuja. (The range of ideas provides a wide selection of solutions.) Ideiden vapaus on usein keskustelun aihe tutkimuksessa ja innovaatioissa.
