Do birds and fowls fly?
By Anatoly Liberman
An etymologist is constantly on the lookout for so-called motivation. Why is a cat called cat, and why do English speakers say tree if the Romans called the same object arbor? As everybody knows, the “ultimate truth” usually escapes us. Once upon a time (about five thousand or even more years ago?) in a hotly debated locality there lived the early Indo-Europeans, and we still use words going back to their partly unpronounceable sound complexes.
