Many linguists have asked themselves this question, and some argue that the word truffle derives from the Latin terrae tufer (excrescence of the earth), although the Romans actually called it terrae tuber. Or it may originate from tufule tubera, the title of a medieval collection dedicated to truffles. From here we can guess how at that time people thought of a sort of link between the truffle and the tuff. The term spread throughout Italy and also in Europe, in fact even today we can clearly see that the same root is also present in English with truffle, in German with Trüffel, in French with truffe, in Spanish with trufa.
