Frequently Asked Questions
What's the difference between 'mar' and 'océano'?
Technically, an 'océano' (ocean) is one of the Earth's five huge bodies of water (like the Atlantic Ocean), and a 'mar' (sea) is a smaller part of an ocean, often partly enclosed by land (like the Mediterranean Sea). In everyday conversation, however, people often use 'mar' and 'océano' to mean the same thing: the big, salty water at the beach.
Why is 'mar' sometimes masculine ('el') and sometimes feminine ('la')?
It's one of Spanish's special cases! The standard, most common form is masculine: 'el mar'. The feminine form, 'la mar', is used in poetry, literature, and by people who have a close relationship with the sea, like fishermen. It gives a more personal, emotional, or respectful feeling. When you're learning, it's safest to always use 'el mar'.
