So, your daughter just got married, or perhaps you're learning Spanish and want to impress your new family? Either way, you need to know how to say 'son-in-law' in Spanish! The most common and widely accepted translation is **'yerno'**.
Think of it as your direct connection to your daughter's happiness! Using the correct term shows respect and affection.
Here are a few examples:
* 'Estoy orgulloso de mi yerno.' (I am proud of my son-in-law.)
* 'Mi yerno es un hombre muy trabajador.' (My son-in-law is a very hard-working man.)
While 'yerno' is the standard, you might occasionally hear variations depending on the region, but sticking with 'yerno' will ensure you're understood everywhere. Now go forth and confidently greet your *yerno*!
