Learn Icelandic: Koma góðir dagar bráðum?

The singular word for day is dagur. It is a masculine noun. To make it a bare plural in the nominative case (used here because it is the subject of the sentence), we drop the singular ending -ur and add the plural ending -ar, giving us dagar.

Why is the adjective góðir used instead of the dictionary form góður?

Adjectives in Icelandic must match the noun they describe in gender, number, and case. Since dagar is a masculine plural noun in the nominative case, the adjective must match. The -ir ending on góðir shows this masculine plural agreement.

Why does the sentence start with the verb Koma?

To form a yes/no question in Icelandic, you swap the subject and the verb. By putting the verb Koma at the very beginning, before the subject góðir dagar, it turns the statement into a question. Literally, it asks: Come good days soon?

How does koma mean 'are coming' instead of just 'come'?

Icelandic does not have a separate continuous tense like the English 'am/is/are doing' pattern. The simple present tense verb koma covers both 'come' and 'are coming'. You just choose the translation that sounds most natural in English context!
