Spanish, like many world languages, has been shaped by centuries of cultural exchange. One fascinating influence comes from Arabic, which left a lasting mark on the Spanish language during the nearly 800 years of Muslim rule in parts of the Iberian Peninsula. As a result, thousands of Spanish words—especially those related to science, architecture, and daily life—have Arabic roots. This influence can still be seen today in common words like almohada (pillow), aceituna (olive), and ojalá (hopefully). Understanding this connection helps us appreciate the rich and diverse history behind the Spanish we speak today.
