materiilor

Materiilor is the genitive and dative plural form of the Romanian noun materie. The base noun materie has several senses in Romanian: matter or substance, a subject or topic studied in school, and a material or substance used in making or analysis. The form materiilor appears in contexts where the noun governs the genitive or dative case in the plural, typically to indicate possession, relation, or classification involving multiple subjects or materials.

In terms of meanings, materiilor can refer to two broad strands depending on context. First, when materie is used in the sense of subjects taught at school, materiilor marks the plural possessive or indirect object relationship, for example in phrases like proprietățile materiilor predate în semestrul curent. Second, when materie is used in the sense of material or substance, materiilor can appear in technical or formal writing to discuss properties or characteristics of several materials, for instance proprietățile materiilor dintr-un set experimental.

Usage notes and scope: materiilor is a formal, grammatically specific form. It contrasts with materii, the nominative plural used for the subject or the materials in isolation, and with materiei, singular genitive/dative. The distinction between senses depends on the surrounding nouns and adjectives, and on whether the discourse treats topics (subjects) or substances (materials). In everyday Romanian, the choice between materiilor and related forms is guided by grammatical role rather than by a fixed semantic split.

Etymology and related terms: materiilor derives from materie, which comes from Latin materia. Related terms include materia (singular), materiile (nominative plural), and material (in the sense of physical material in Romanian). See also Materie and Material for broader context.
