Learn Hardcore Esperanto: La domo estas granda.

In Esperanto, la is the definite article (just like the in English). There is no indefinite article in Esperanto, so you only use la when you specifically want to say the.

Why does domo end in -o?

In Esperanto, nouns always end in -o (or -oj in the plural, -on for accusative singular, etc.). This consistent ending signals that the word is a noun.

Why doesn't domo start with a capital letter?

Esperanto follows the general convention of capitalizing only the first letter of a sentence and proper nouns (such as names of people or countries). Common nouns like domo do not need a capital letter unless they appear at the start of a sentence.

Why is the adjective granda placed after the noun?

In Esperanto, you can put the adjective either before or after the noun. Both La domo estas granda and La granda domo are correct. Position is flexible, so it’s mostly a matter of style or emphasis.

Why does granda end in -a?
