Questions & Answers about Maðurinn tekur kjötið úr frystinum.
Why do we use úr in this sentence instead of frá?
The preposition úr specifically means moving something out of a contained space, like taking meat out from inside a freezer. If you used frá, it would just mean moving away from the freezer's general location.
What case is frystinum in, and why?
It is in the dative case because the preposition úr always forces the noun that follows it into the dative. The base word is frystir (freezer), which becomes frysti in the dative. Adding the dative masculine definite article makes it frystinum.
Why doesn't the word kjötið change its ending if it is the object being taken?
It actually is in the accusative case here! However, kjöt is a neuter noun. Neuter nouns always have the exact same form in the accusative case as they do in the nominative case, so kjötið looks the same whether it is the subject or the object.
What is the dictionary form of the verb tekur?
The dictionary form is taka (to take). Here it is conjugated as tekur because the subject maðurinn (the man) is third-person singular, which causes a vowel change from a to e in the present tense.
