at a disadvantage

词义解析

本义指在竞争、对抗或比较中处于不利条件或劣势地位。引申义可表示因外部条件或自身原因，在做事时受到阻碍或缺乏优势。例如，在比赛中因经验不足而处于不利地位，或因经济条件差而在教育竞争中处于劣势。

字源分析

前缀dis-表示“否定、相反”，advantage源自拉丁语advantagium，意为“优势、有利条件”。因此disadvantage意为“不利条件”，at a disadvantage意为“处于不利条件之中”。记忆时可将disadvantage拆解为dis（否定）+advantage（优势），即“没有优势”。

常见语境

常用于正式或半正式场合，如学术写作、新闻报道、商务讨论中，表示客观的不利状况。在口语中较少使用，多用于书面表达。语气中性，不带强烈感情色彩。

用法须知

该短语通常作表语或状语，后接in、of等介词。常见句型：be at a disadvantage (in...)，put/place someone at a disadvantage。易错点：注意介词搭配，如“at a disadvantage”不可写为“in a disadvantage”；且后接名词时常用of，如“at a disadvantage of”。

同义词区别

与at a disadvantage相近的有in a weak position、at a loss、out of luck等。in a weak position更强调地位薄弱；at a loss强调困惑或不知所措；out of luck强调运气不佳。at a disadvantage侧重于客观条件不利，而in a weak position可能包含主观判断。

易错提醒

该短语为中性表达，不带褒贬。常用于描述竞争、比较或处境，但不可滥用。避免与“at a disadvantage”混淆为“处于劣势”而误用于描述个人能力不足，应区分“条件不利”与“能力不足”。

• be at a disadvantage
• put/place someone at a disadvantage
