Danish is a Germanic language. This is good news for you, because you already know at least one other Germanic language. English is also a Germanic language.
There is a huge amount of crossover between Danish and English, but they are still different enough that you won’t be able to understand very much without studying Danish.
Fortunately, it’s much easier to learn a new way to say or spell a word than it is to learn an entirely new word. My guess is that about 40 percent of Danish is substantially the same as English, and that will make it much easier for you to learn Danish. Take the common English greeting, the word “hi,” and compare it to the Danish word that means the same thing, “hej.” They sound more similar than the spellings would indicate.
