How do you pronounce it?

/ˈɡwau en ˈseɾjo/

Did you know?

  • While English speakers use 'wow' to express amazement, the Spanish guau is strictly an onomatopoeia for a dog's bark. Using it to express surprise is a relatively recent adoption from English.
  • In certain Latin American contexts, instead of ¿en serio?, you might hear ¿es neta? In Mexican slang, 'la neta' means 'the truth', making '¿es neta?' a very common way to say 'really?'
  • While guau is used in some regions, many Spanish speakers prefer ¡hala! or ¡ostras! to express the same level of amazement.

Examples in context
