How do you say "lucky you" in Spanish?
I've often heard the phrase "¡¿Quién como tú!?" to express the idea of "Lucky you!"
Also, "Tienes suerte." would be "You're lucky." or "¡Qué suerte!" for "What luck!"
The site has a wonderful "Translation" section that will allow you to input the exact phrase and obtain the English translation. At the top of the screen, select translation and then input the phrase in the box. Next, hit the Spanish to English button and it will spit out the English translation. Try it, it's great!!
