“have no alternative but to do”的核心语义是“因缺乏其他可行选项，不得不采取某一特定行动”，强调“无替代性选择”与“行动的必然性”。其固定搭配为“have no alternative but + 动词不定式（to do）”，若主句中存在实义动词“do”的某种形式（do/does/did/done），but后可省略to（如“He did nothing but wait”），但“have no alternative but”中“have”非实义动词do，故通常需保留to，即“have no alternative but to do”。
词源溯源“alternative”源自拉丁语“alternare”（意为“交替、轮流”），16世纪进入英语，最初仅表示“两者择一的”；“have no alternative but”这一短语于18世纪末开始广泛使用，最早见于英国政治家的演讲与正式文书（如议会提案），用于表达“在两种或多种可能中因排除其他选项而只能选择其一”；19世纪后，短语逐渐扩展到日常语境，弱化“两者择一”的原始含义，强化“无奈之下的唯一选择”。
