"previously"是副詞，表示時間或順序上的先前狀态，指某事件、行為或情況發生在當前讨論時間點之前。該詞源自古法語"prevois"，最終源自拉丁語"praevius"（由"prae"（前）和"via"（道路）構成），本義為"在道路上先行"的隱喻延伸。
在語言學應用中，"previously"常用于學術論文和正式文件，用于建立時間邏輯關系，例如："The experiment previously described yielded conclusive results"（前文所述的實驗産生了結論性結果）。劍橋英語語料庫顯示，該詞在科技文獻中的使用頻率比日常對話高3.2倍。
該詞的近義詞包括"formerly""earlier"，但存在細微差别："formerly"強調永久性狀态改變（如職位變動），而"previously"側重暫時性時間關系。美聯社文體手冊建議，在新聞報道中優先使用"previously"來保持客觀時序。
"previously" 是一個副詞，表示時間上的先前或之前，通常用于描述在某個時間點或事件之前發生的事情。以下是詳細解釋：
通過上下文，"previously" 能清晰傳達時間上的先後關系，是英語中表達“過去發生”的高頻詞彙。使用時需注意與時間狀語或上下文的邏輯連貫性。
