Etymology: The eel is one of the oldest words in the English language, and its origins are a genuine mystery. Its Old English form "ǣl" goes back to a Proto-Germanic "*ēlaz", and the root has no traceable source beyond that point. Scholars have not been able to link it convincingly to any older language, so the word stands as a survivor from a very distant past. What is clear is that the word has remained remarkably stable. Speakers of English, Dutch, German, Swedish, Danish, Norwegian, Icelandic and Faroese all share a version of it, a reminder that the Germanic languages have long agreed on what to call this slippery fish. The Dutch "aal" and the Swedish "ål" look and sound very much like the English word, and all of them trace back to the same ancestral form.
