Etymology

From *eh (‘but, except’, from Proto-Indo-European *h₁eǵʰs/*h₁eḱ (s), ‘out’) + *þau (‘in that case’, from PIE *tó-we, from PIE *to-, ‘this, that’ + *-we, ‘or’). The first element *eh is debated: many accounts assume *ef- matching West Proto-Germanic f-variants (e.g. Old English ofþe, Old Saxon eftha), possibly influenced by the Proto-Germanic conditional particle family (‘if’); however, Gothic aiþþau is often taken to point to an earlier *ehþau with subsequent assimilation producing *-þþ-. The second element *þau is less controversial, though there are many other competing theories on its PIE heritage.
