What Spanish words that start with W?
I got this from http://en.allexperts.com/q/Spanish-Language-1551/spanish-word.htm
"Interestingly, there are no actual Spanish words that begin with the letter "W". However, there are a few words used in Spanish that begin with "w", but they are words borrowed from other languages, often English. For example, "winsurf", "walkman" and "western". I hope that answers your question."
Use About.com for Spanish.
I got this from Vox Diccionario de Primaria de la Lengua Española:
wáter = 1. Es otra forma de escribir: váter. 2. inodoro; retrete; servicio.
If you check a Spanish dictionary, you will find a handful of words but they are words that were borrowed from other languages and they are not actually Spanish words.
its the same with words that start with K, they are only words borrowed from other languages.
