"We go to the sea."
Translation:Wir gehen zum Meer.
As Wataya said, in a new language (like german for us) the prepositions are not translatable and that is the biggest confusion... once you realize this you start just learning them by memory and use, because there aint no other way.... When you translate them you get confused... My mother language is spanish and from spanish to english its the same deal, some are relatable, but not entirely translatable...
"Zu" might roughly translate to "to" in english. But germans say. Ich bin zu Hause. Translated it would mean, i am to home... Clearly thats not what the german sentence meant... there are many other examples like that one.
