where did the leeward islands get their name
Leeward Islands The name of this island group, Leeward Islands, dates from previous centuries, when sailing ships were the sole form of transportation across the Atlantic Ocean. In sailing terminology, "windward" means towards the source of the wind, while "leeward" is the opposite direction. In the West Indies, the prevailing winds, known as the trade winds, blow out of the southeast. Therefore, an island to the northwest, such as Puerto Rico, would typically be leeward of an island to the southeast, such as Antigua, and conversely, Antigua would typically be windward of Puerto Rico, but leeward of Guadeloupe and Martinique.
Polka dot It is likely that the term originated in popularity of polka dance at the time the pattern became fashionable, just as many other products and fashions of the era also adopted the "polka" name.[1]
