層次 (語言學)

層次（拉丁文：stratum）喺語言學入面係一種語言，透過接觸，影響到或者受影響跟另一個語言嘅。底層（拉丁文：substratum）係種語言有權力或者威望低過其他語言嘅，而頂層（拉丁文：superstratum）係種語言有權力或者威望高過嘅。底層語言同頂層語言互相都有影響，但係方式唔同。附褦層（拉丁文：adstratum）係種語言戥隔籬第二種語言有接觸，但冇乜高過或者低過嘅威望。隻概念「層次」初初發展由意大利語言學家Graziadio Isaiah Ascoli（1829–1907），並喺1932年知名喺英語世界，憑藉份著作寫由另開兩位作者嘅。^[1]

兩隻概念都適用於一種侵擾語言建立自己嘅地位喺另一笪領土上高，通常係出於移民。頂層情況（本地話一路保持，侵擾話消失）或者底層情況（本地話消失，侵擾話一路保持）通常變得明顯只會喺幾代人之後，期間侵擾語言存在於diaspora嘅文化裏頭。爲了等侵擾話持續得落去（底層情況)，啲移民一係獲取政治精英地位，一係移民夠大量對於當地人口來講（即侵擾着定性爲侵略或者殖民；譬如羅馬帝國催生羅曼各語喺意大利之外，取代丟高卢話與及其他印歐語^{[註 1]}）。頂層嘅例子有啲精英入侵人口但最終採用了本土下層語言嘅。比如法國勃艮地人同埋法蘭克人，佢哋最終放棄了佢哋嘅日耳曼話，而改用了啲其他印歐語屬羅曼語分支嘅，同時喺隻過程中影響了當地語言好深。
