The Spanish language doesn’t have a letter that corresponds precisely to the English letter “W”. As a substitute, the “W” sound is usually represented by the letter “V”. For instance, the English phrase “water” is “agua” in Spanish, and the English phrase “window” is “ventana” in Spanish.
Nonetheless, there are some exceptions to this rule. In some circumstances, the “W” sound is represented by the letter “U”. For instance, the English phrase “William” is “Guillermo” in Spanish. Moreover, the “W” sound can generally be represented by the letter “GU”. For instance, the English phrase “battle” is “guerra” in Spanish.
