luustojen

Luustojen is the genitive plural form of luusto, a Finnish noun meaning skeleton or skeletal system. It is used when referring to the skeletons of multiple organisms or to the skeletal systems in a plural or collective sense, such as in scientific or descriptive writing.

Grammatical notes: luusto forms plural luustot in the nominative and luustojen in the genitive plural. The singular genitive is luuston. The suffix -ojen is typical for genitive plural for nouns ending in -o. This form appears in contexts such as anatomy, veterinary medicine, and paleontology to indicate “of the skeletons” or “the skeletons’.”

Usage and context: luustojen is common in academic and clinical texts when multiple skeletons are discussed. Examples include phrases like luustojen rakenne (the structure of the skeletons), luustojen terveys (the health of the skeletons), and luustojen kehitys (the development of the skeletons). It can also appear in possessive constructions referring to several individuals or species, for instance luustojen ravitsemus (the skeletons’ nutrition).

Related terms: luusto refers to the skeleton in general, often in singular contexts. Ulkoluusto denotes an exoskeleton in animals such as insects and crustaceans, while endoskeleton is typically translated in Finnish as part of the broader anatomical vocabulary. Luustojen therefore sits within Finnish anatomical and biological terminology as the plural genitive form used to discuss multiple skeletons.
