you're welcome

"De nada" is the most common way to respond to "gracias" (thank you). Literally translated as "of nothing," it conveys the idea that the favor or service provided was so small that it is worth nothing, reflecting a sense of humility and politeness. It is highly versatile and works in almost any situation, from speaking with close friends to professional settings. While it is the standard response, in very formal or emphatic situations, people might also use "no hay de qué" or "un placer."
