Frequently Asked Questions
If 'castillo' is a castle, how do I say 'palace'?
While 'castillo' can sometimes be used for an extremely grand residence, the more precise Spanish word for a royal or official residence is 'palacio'. They are often similar buildings, but 'palacio' emphasizes the residence aspect, while 'castillo' emphasizes the fortification.
Why does the 'll' sound like a 'y'?
The 'll' in Spanish, called 'elle,' is a special sound that developed historically. In most parts of the Spanish-speaking world, it is pronounced exactly like the 'y' sound in English words like 'yes' or 'yellow.' This is known as 'yeísmo'.
