Lyijyisten

Lyijyisten is a Finnish linguistic term referring to the genitive plural form of the adjective lyijyinen, meaning lead-containing or lead-based. In Finnish, adjectives agree with the noun they modify in number and case; when the noun is plural and in the genitive case, the adjective takes the form lyijyisten. The word thus functions as a descriptor in noun phrases rather than as a standalone noun.

Etymology and morphology: The form derives from the root lyijy (lead) combined with the to-forming suffix -inen to create an adjective meaning containing lead or made of lead. The genitive plural ending lyijyisten is used when the associated noun is plural and in a genitive relationship, for example in expressions like “lyijyisten esineiden pitoisuus” (the concentration of lead-containing items).

Usage and context: Lyijyisten appears primarily in technical, scientific, or descriptive Finnish to indicate lead content. It is not used alone; it accompanies a noun in a genitive construction. Typical contexts include discussions of materials, products, or substances that include lead, as in safety assessments, quality controls, or regulatory descriptions.

Examples:

- lyijyisten aineiden pitoisuus (the concentration of lead-containing substances)

- lyijyisten esineiden turvalisuusarviointi (the safety assessment of lead-containing items)

Note: Lyijyisten is a grammatical form rather than a standalone concept; its interpretation depends on the noun it modifies.
