Learn Hardcore Icelandic: Veðrið er heitt.

Veðrið translates to "the weather." It comes from the base word veður, meaning "weather," with the definite article attached as the suffix -ið to indicate "the."

What does heitt mean, and why is it in that particular form?

Heitt means "hot." It appears in the neuter singular form because it agrees with veðrið, which is a neuter singular noun. In Icelandic, adjectives must match the gender and number of the noun they modify.

Why does Icelandic use a suffix for the definite article as seen in veðrið instead of a separate word like in English?

Icelandic indicates definiteness by adding a suffix to the noun rather than using a separate word. In this case, veður becomes veðrið when the definite article is added, making it "the weather."

What is the role of er in the sentence?

Er is the present tense of the verb vera (to be) and functions as a linking verb in the sentence. It connects the subject veðrið with the predicate adjective heitt.

Can you explain the overall grammatical structure of "Veðrið er heitt"?

Subject: Veðrið means "the weather."
