stratifitseeritud

Stratifitseeritud is a Estonian adjective meaning organized in layers or strata, or consisting of multiple distinct layers or levels. It is formed from the verb stratifitseerida, which derives from the English stratify and ultimately from Latin strata meaning layers. The term is used in formal and technical language to describe structures, systems, or samples that are divided into strata.

In geology, stratifitseeritud rocks exhibit visible layering due to sedimentary deposition or metamorphic processes. In biology and medicine, stratified epithelia consist of several cell layers, as opposed to single-layered epithelia; examples include stratified squamous epithelium lining the skin and oral cavity. In statistics and research methodology, stratified sampling divides a population into strata to improve representativeness, with samples drawn from each stratum. The term also appears in sociology and demography to refer to stratified societies characterized by hierarchical social layers.

In everyday Estonian, stratifitseeritud is most common in technical discourse. A closely related noun pair is stratifitseerimine (the process of stratifying) and stratifikatsioon (stratification), used in more formal or scholarly texts. When describing physical structures more generally, speakers may opt for synonyms like kihiline, but stratifitseeritud emphasizes deliberate or systematic layering.
