The letter “k” is not traditionally part of the Spanish alphabet and appears almost exclusively in loanwords, particularly from other European languages, and in words originating from indigenous languages of the Americas. Examples include “kilo,” “kayak,” and “kerosene,” alongside words like “kiosco” (kiosk). Words from indigenous languages include “Kuna” (an indigenous people of Panama and Colombia). These terms often retain their original spelling, introducing the “k” into Spanish vocabulary.
The presence of these terms reflects the dynamic and evolving nature of language, demonstrating how Spanish absorbs and adapts vocabulary from other cultures. This incorporation of foreign terms enriches the language and provides a linguistic window into historical interactions and cultural exchange. Understanding the origins and usage of these words provides valuable insights into the historical and cultural influences shaping the Spanish language.
