Learn Icelandic: Við verslum og kaupum allt kjötið.

The word allur has to match the gender, number, and case of the noun it describes. Because kjöt (meat) is a neuter noun in the singular, we use the neuter singular form, which is allt.

What case is allt kjötið in this sentence?

It is in the accusative case because it is the direct object of the verb kaupa (to buy). For neuter words, the accusative form looks exactly the same as the nominative (subject) form.

Why do we add the definite ending -ið to kjöt after allt?

In Icelandic, if you want to say 'all the' followed by a noun, you must attach the definite article to the noun. Allt kjötið means 'all the meat' (a specific amount). If you just said allt kjöt, it would mean 'all meat' in general.

What is the difference between versla and kaupa?

They are related but have different meanings. Versla refers to the general activity of shopping, while kaupa means to actually buy or purchase specific items.

As a quick refresher, why do both verbs end in -um?
