Typpisiä

Typpisiä is a Finnish adjective meaning “nitrogen-containing” or “nitrogenous.” It describes substances that include nitrogen atoms. The form typpisiä is the partitive plural of typpinen and is used with plural nouns in the partitive case, for example typpisiä yhdisteitä.

In scientific contexts, typpisiä is common in chemistry, biochemistry, environmental science, and related fields. It describes both organic and inorganic compounds that contain nitrogen, and it is used to distinguish nitrogen-containing substances from those that do not contain nitrogen. The term appears in discussions of chemical properties, reactions, and classifications.

Morphology and grammar: The base adjective is typpinen. In plural nominative it becomes typpiset, and in plural partitive it becomes typpisiä. In singular, the nominative form is typpinen and the partitive singular is typpistä. The word is formed from typpi (nitrogen) with the adjectival suffix -nen, following standard Finnish adjective formation rules.

Usage notes: Typpisiä is primarily found in technical language and scientific writing. It helps specify the presence of nitrogen in a substance without naming individual compounds. In everyday Finnish, more general phrases may be used, but typpisiä remains common in formal, precise descriptions of chemical composition.
