是英語形容詞,基本含義為“不育的;無菌的;貧瘠的;枯燥乏味的”,英式發音為[ˈsteraɪl],美式發音為[ˈsterəl]。作為GRE/TOEFL核心辭彙,其名詞形式為sterility,具有大小寫變形規則。
該詞在不同領域有多重套用:醫學場景中指無菌狀態(如sterile water/gloves),生物學描述繁殖能力缺失(如sterile insect technique)或植物生理特徵(如pollen sterile blossoms),農業領域用於貧瘠土地的描述。抽象語境中可表示缺乏創造力或無效(如sterile debate)。其同義詞包括sanitary、barren,反義詞為fertile。
詞源可追溯至拉丁語sterilis(不結果實的),原始印歐語詞根*ster-(僵硬的)衍生出“貧瘠”與“滅菌”的引申義。16世紀通過法語stérile傳入英語,1530年代擴展至人類生育語境,1877年確立現代醫學“無菌的”定義。
