Scrabble?! SIES

Definitions of SIES in various dictionaries:

A siesta (Spanish pronunciation: [ˈsjesta]) (Spanish, meaning "nap") is a short nap taken in the early afternoon, often after the midday meal. Such a period of sleep is a common tradition in some countries, particularly those where the weather is warm. The siesta is historically common throughout the Mediterranean and Southern Europe. It is the traditional daytime sleep of Spain and, through Spanish influence, the Philippines, and many Hispanic American countries. In Dalmatia (coastal Croatia), the traditional afternoon nap is known as fjaka (from Italian fiacca). The Spanish word siesta derives originally from the Latin word hora sexta "sixth hour" (counting from dawn, hence "midday rest"). Factors explaining the geographical distribution of the modern siesta are high temperatures and heavy intake of food at the midday meal. Combined, these two factors contribute to the feeling of post-lunch drowsiness. In many countries that practice the siesta, the heat can be unbearable in the early afternoon, making a midday break at home welcome.
