Learn Icelandic: Asía er stærsta heimsálfan. - Asia is the largest continent.

Stærsta is the weak form of the superlative adjective (meaning "largest"). In Icelandic, when an adjective comes before a definite noun (a noun with "the" attached), you must use the weak declension. Because heimsálfan is a feminine noun in the nominative case, the correct weak ending is -a.

Where is the word for "the" in "the largest continent"?

Unlike English, which uses a separate word before the adjective, Icelandic attaches the definite article directly to the end of the noun. The -n at the end of heimsálfan is the article. The combination of the weak adjective stærsta and the suffixed noun heimsálfan translates to "the largest continent".

How is the compound word heimsálfan built?

It is made of two base words: heimur (world) and álfa (continent), plus the definite article -n. They are joined using the genitive (possessive) case of heimur, which adds the connecting -s to make heims-. Literally, the word means "the world-continent".

Why doesn't Asía have a definite article attached to it?

Just like in English, proper nouns for most countries and continents don't take a definite article in Icelandic. You simply say Asía, not Asían, even when talking about it as a specific place.
