 The Puerto Rico of today has come to form some of its own social customs, cultural matrix, historically rooted traditions, and its own unique pronunciation, vocabulary, and idiomatic expressions within the Spanish language, known as Puerto Rican Spanish.Even after the attempted assimilation of Puerto Rico into the United States in the early 20th century, the majority of the people of Puerto Rico feel pride in their nationality as "Puerto Ricans", regardless of the individual's particular racial, ethnic, political, or economic background.Many Puerto Ricans are consciously aware of the rich contribution of all cultures represented on the island.
