The letter “k” is not native to the Spanish alphabet and appears almost exclusively in loanwords, primarily from other European languages (like German and English) and indigenous languages of the Americas. Examples include “kilo” (kilogram) and “kayak.”
While infrequent, these borrowed terms play a vital role in expanding the lexicon, reflecting cultural exchange and the adoption of new concepts and technologies. Understanding their origins provides valuable insight into the evolution of the Spanish language and its interaction with other cultures throughout history. This relatively small subset of vocabulary offers a fascinating lens through which to explore linguistic adaptation and the dynamic nature of language itself.
