Learn Icelandic: Stefnumótið er rómantískt.

Adjectives in Icelandic must agree with the gender of the noun they describe. Because stefnumót is a neuter noun, the masculine dictionary form rómantískur drops the -ur and takes the neuter ending -t.

What is the literal translation of the compound word stefnumót?

It combines stefna (a direction, orientation, or summons) and mót (a meeting or gathering). While it translates to "date" in this romantic context, it is also the everyday word for a standard "appointment," such as a doctor's visit.

How is "the" expressed in stefnumótið?

Icelandic usually attaches "the" to the end of the word rather than using a separate article. The base neuter noun is stefnumót. By attaching the neuter definite suffix -ið, it becomes stefnumótið (the date).

What case are the words in this sentence in?

Everything is in the nominative case (the default dictionary case). The verb vera (to be) is a linking verb, which means it doesn't force the noun or the adjective following it into a different case like the accusative or dative.
