stratum

Stratum是源自拉丁語的英語名詞，複數形式為strata，原意為“鋪設層”，指由物質或抽象元素構成的層次結構。其核心含義廣泛套用於地質學、社會學及生物學等領域。

在地質學中，stratum指由沉積作用形成的岩石或土壤層，具有明確的時間序列和物質特徵，如含水岩層與交錯地層。社會學層面，該詞描述因經濟、教育等因素形成的社會等級群體，強調層級差異，如“社會各階層”或“貧困階層”。生物學領域則衍生出角質層（stratum corneum）等組織層級概念。

該詞於17世紀被引入地質學描述岩層疊加現象，詞根“stratus”在拉丁語中兼具“覆蓋”與“延展”意象，後逐漸擴展至社會學分析。其複數形式strata及形容詞stratal等變形辭彙進一步鞏固了跨學科套用的層次化特徵。
