Translation:The cat runs around the restaurant.
Could you use the preposition for around ("um") so that it would be "Ritheann an cat um na bialainne"? Or would that mean something else? ALSO: what would the Nominative Case for this sentence be? Because I thought that the Genitive Case is suppose to show a relationship between 2 nouns? To me this sentence sounds like it is in the Nominative Case, not the Genitive... Am I missing something?
