Questions & Answers about Bróðirinn er sterkur.

Why does bróðirinn end with -inn instead of using a separate word like “the”?

In Icelandic the definite article is suffixed to the noun rather than being a separate word. For masculine nouns in the nominative singular you add -inn.

• bróðir = “brother” (indefinite)
• bróðirinn = “the brother” (definite)

Why is the adjective sterkur not sterkurinn when it follows er?

Adjectives used predicatively (i.e. after a form of vera “to be”) stay in their base (indefinite) form but still agree in gender, number, and case. They never take the definite suffix. Hence:

• Bróðirinn er sterkur. “The brother is strong.”

What gender, number, and case are bróðirinn and sterkur in this sentence?

Both are masculine nominative singular.

• Bróðirinn (subject of the verb) → masc. nom. sg.
• sterkur (predicative adjective) → masc. nom. sg., agreeing with the noun
