"previously"是副词，表示时间或顺序上的先前状态，指某事件、行为或情况发生在当前讨论时间点之前。该词源自古法语"prevois"，最终源自拉丁语"praevius"（由"prae"（前）和"via"（道路）构成），本义为"在道路上先行"的隐喻延伸。
在语言学应用中，"previously"常用于学术论文和正式文件，用于建立时间逻辑关系，例如："The experiment previously described yielded conclusive results"（前文所述的实验产生了结论性结果）。剑桥英语语料库显示，该词在科技文献中的使用频率比日常对话高3.2倍。
该词的近义词包括"formerly""earlier"，但存在细微差别："formerly"强调永久性状态改变（如职位变动），而"previously"侧重暂时性时间关系。美联社文体手册建议，在新闻报道中优先使用"previously"来保持客观时序。
"previously" 是一个副词，表示时间上的先前或之前，通常用于描述在某个时间点或事件之前发生的事情。以下是详细解释：
通过上下文，"previously" 能清晰传达时间上的先后关系，是英语中表达“过去发生”的高频词汇。使用时需注意与时间状语或上下文的逻辑连贯性。
