Spanish word that starts with a w?

Answer 1

Originally, the Spanish language did not use the letter w. So, all words with that include w are directly taken from other languages (Spanglish, etc).

These include:

walkie-talkie

walkman

waterpolo

web (as in the internet)

whiskey

windsurfista

Answer 2

wat (electrical 'watt')

some German words, e.g. 'wagneriano', but also written 'vagneriano'
