"The girl eats a lemon."
Translation:Pigen spiser en citron.
Danish and English (along with many other Western European languages) are Germanic languages, so of course there are lots of similarities. A thousand years ago, English (Old English) and Danish (Old Norse) were mostly mutually intelligible.
Even today, you just have to look at a simple sentence in a few Germanic languages to see the similarity:
Danish: Hav en god dag
English: Have a good day
German: Hab einen guten Tag
Dutch: Heb een goede dag
Swedish: Ha en bra dag
