Learn Hardcore Icelandic: Kaffihúsið er opið.

It’s the definite article attached to a neuter noun, so kaffihús (“coffee house”) becomes Kaffihúsið (“the café”). Icelandic marks definiteness by suffixes: neuter nom. sg. adds -ið.

Is opið a verb or an adjective here?

It’s an adjective (from opinn, “open”) used predicatively with vera to describe the state of the subject.

Why does opið end in -ið rather than -inn or -in?

Hence opinn (m.), opin (f.), opið (n.).
