"in no uncertain terms" 这个短语的意思是“用明确无误的语言”、“直截了当地”，强调说话的方式非常清晰、坚决，不留任何歧义或怀疑的余地。 例句： The manager told him in no uncertain terms that he must finish the report by Friday. （经理明确无误地告诉他，必须在周五前完成报告。） She refused his invitation in no uncertain terms, leaving no room for misunderstanding. （她直截了当地拒绝了他的邀请，没有任何误解的空间。）
