Questions & Answers about Ég borða oft ost heima.
The dictionary word for cheese is "ostur". Why does it change to ost here?
In this sentence, the cheese is the direct object—it's the thing being eaten. This means it takes the accusative case. For many masculine nouns that end in -ur (like ostur), you simply drop the -ur to make the accusative form. That leaves us with the bare noun ost.
Why does oft come after the verb instead of before it, like in "I often eat"?
Why is "at home" translated as heima rather than just heim?
Icelandic makes a strict difference between being somewhere and moving somewhere. Heima means you are stationary "at home" doing something, like eating. If you were actively walking or driving toward your house, you would use the motion word heim (homewards) instead.
Why does the verb borða look exactly like its dictionary form here?
The infinitive (dictionary form) of the verb "to eat" is að borða. Conveniently, for a large group of Icelandic verbs that end in -a, the "I" form (ég) in the present tense is identical to the infinitive. So, no extra changes are needed to say Ég borða!
