An Understandable Neighbor
Anyone who speaks Swedish or travels there quickly finds out that Swedish, Danish, and Norwegian languages are mutually understood between speakers. So learning Swedish is beneficial for anyone who has a goal of being multi-lingual.
Say Thank You
There is no real word for please in Swedish. The closest word is “Tack” which means “Thank you” but the word please doesn’t translate into Swedish. Saying “tack” in a respectful tone is the best way to solve this dilemma. Swedish also has a smaller vocabulary compared to other languages in part because of its concentrated population of speakers.
Articles After Nouns
One of the most difficult things to learn in a new language is figuring out which article goes with the noun. In Swedish the article comes after the noun. So “the dog” becomes “hund” and “en” or “hunden” making the process a little easier to remember.
