Jr is incorrectly written, and should be written as "Jr." being its meaning: Jr.: Abbreviation for junior, Word of English pronounce yunior, which translates to Spanish Youth, juvenile, minor. This word is used mainly in English-speaking countries and in some countries in Central and South America, to distinguish the son of the father when both carry the same name. Example: If the father is called Juan-Carlos Torres, and placed his son the same name, i.e., Juan Carlos, to the latter, to distinguish it from the father they will call him on their families and friends, Juan Carlos Torres Junior, or Juan Carlos Junior.
