摘要：They asked him to leave—in other words he was fired. (他们要求他离开，换句话说，他被解雇了。 )[牛津高级学者辞典]

in other words的字面义是“以其他单词[的方式]”，对应汉语“换句话说”，如

【例句1】They asked him to leave—in other words he was fired. (他们要求他离开，换句话说，他被解雇了。 )[牛津高级学者辞典]

【例句2】They're letting me go—in other words, I've been sacked. (他们要让我走——换句话说，我被解雇了。)[牛津高级学者辞典]

【例句3】So he is a fraud, a common thief in other words. (因此他是个骗子，换言之，是个普通的小偷。)[朗文当代英语词典]

【例句4】He was economical with the truth - in other words, he was lying. (他隐瞒了真相，换句话说，他在撒谎。 ) [剑桥高级学者辞典; economical的字面义是“经济的”，引申“不说话”]

【例句5】The mobile library services have been reorganised–in other words, they visit fewer places. (移动图书馆服务已经重组，换句话说，他们访问的地方更少了。)[柯林斯高级学者辞典]

【例句6】The tax only affects people on incomes of over $200,000 – in other words, the very rich. (该税只影响收入超过20万美元的人，换句话说，就是非常富有的人。)[朗文当代英语词典]

因为“换句话说”的常态是需要多个单词，所以in other words的words是复数。若抬杠真是只说了一个单词，那也遵从典型习惯。
