"A girl is a child."
Translation:En jente er et barn.
What is the difference between en and et? I assumed that it was similar to English, where words starting with vowels have "an" in front instead of "a", and that "et" is the equivalent of "an", but now in this sentence it's in front of barn, which does not start with a vowel. It didn't seem like there was a feminine and masculine difference, because "en" is used for both "en mann" and "en kvinne". Could anyone explain the difference?
Their usage is similar to "the" and "a/an" in English, meaning that they determine something already familiar/specific (definite) or something vague/general (indefinite).
