The word tapas comes from the verb tapar, to cover, and the noun tapa, cover or lid. There are many legends that attempt to explain the roots of tapas, although their true origin is unknown. One of these legends claims that tapas were conceived out of a need to cover one's glass to keep the flies out. But were there really more flies in Spain than in other countries? Others state that tapas "cover" one's stomach, i.e. line it with some food, to protect it from the alcohol. (One of the most valuable pieces of advice an old tavernero gave me when I first arrived in Spain in 1998 was "always eat more than you drink and you'll never get drunk".) Yet another legend says that tapas were meant to "cover" the appetites of field workers; they would nibble on something in order to regain their strength to keep working.
