Learn Icelandic: Bakarí Jóns og Sigrúnar er lokað í dag. - Jón and Sigrún's bakery is closed today.

In Icelandic, the thing being owned usually comes first, followed by the owner. Instead of saying "Jón's bakery", the Icelandic phrasing is more like "Bakery of Jón".

Why do the names get different possessive endings (Jóns versus Sigrúnar)?

Icelandic possessive (genitive) endings depend on the gender and word group of the noun. Jón is a masculine name and takes the common -s ending, which looks just like English. Sigrún is a feminine name, and feminine words often take the -ar ending to show ownership.

Do both names really need to be in the possessive form?

Yes! In English, we usually just put the possessive "s" on the very last name, like "Jón and Sigrún's". But in Icelandic, every single owner in the list must be put into the genitive case. That is why both names change form here.

Why is the word for closed spelled lokað here?

Descriptive words (adjectives) have to match the gender of the noun they describe. The word bakarí is a neuter noun. Because of this, the adjective takes the neuter ending -ð, making it lokað instead of the masculine dictionary form lokaður.
