Substratului

Substratului is the genitive/dative singular form of substrat in Romanian. The base noun substrat refers to a base layer, underlying material, or medium on which processes occur or things rest. The form substratului appears in phrases indicating possession or an indirect object, for example componenţa substratului or adăugarea nutrienţilor substratului.

In scientific and technical contexts, substratul designates the material that supports or underlies a system. In geology and soil science, substratul (and substratul natural) means the underlying geological or soil layer that supports vegetation or constructions. In biology and microbiology, a substrate is the substance on which an organism grows or a chemical reaction occurs, such as a growth substrate for cultures or a substrate for enzymes. In horticulture and agriculture, substratele de cultură refer to growth media used for plants or microorganisms.

In linguistics, substratul denotes a language that leaves an imprint on another language through contact, influencing phonology, vocabulary, or syntax. Romanian usage follows the same pattern as other Latin-derived terms: substratului marks the possessive or dative sense in contexts like componenţa substratului sau influenţa substratului lingvistic asupra limbii cultivate.

Usage notes: substrat is masculine; substratul is the definite nominative/accusative form, while substratului marks the genitive/dative singular. The term appears across disciplines seeking to describe an underlying base, foundation, or background layer, whether physical, biological, or linguistic.
