Questions & Answers about Este es el volcán más grande del mundo.
Why does it say del mundo instead of en el mundo for 'in the world'?
When making relative superlatives in Spanish (saying something is the 'most' or 'biggest' in a group or place), you use de instead of en. So, 'the largest in the world' becomes el más grande de el mundo, which contracts into del mundo.
How does the phrase el volcán más grande translate to 'the largest volcano'?
Why is the first word Este rather than Esto?
Este is the masculine singular form of 'this'. It is used here because it refers directly to volcán, which is a masculine noun. The word esto is neutral and is only used for abstract ideas or unknown objects, not specific nouns you can name.
How can I tell that volcán is a masculine noun since it does not end in -o?
