Umami (pronounced oo-MAH-mee) has been called the fifth taste, joining the traditional quartet of salty, sweet, bitter and sour.

The word Muse comes from Latin MÅ«sa, which in turn is from Greek Mousa. In Greek dialects, this word is found in the variant forms mÅsa and moisa, and together these indicate that the Greek word comes from an original *montwa. As to the further origins of this form, a clue is provided by the name of Mnemosyne, the goddess of memory and mother of the Muses.
