Dutch as an Influencer
The English language has much to thank Dutch for. Dutch settlers came to the American colonies during the 17th century and added a few words to the vocabulary. Words like Santa Claus, waffle, blink, cookie, bazooka, gin, and iceberg wouldn’t exist without it.
Learning Dutch is Easier for English Speakers
Given the influence Dutch has had on English, it makes sense that Dutch is easier for speakers to learn. This is in part because Dutch, German, and English have similar roots. It’s between English and German. It only has two definite articles, “de” and “het” to English’s one “the” and German’s “der”, “die”, “das”. But Dutch words are more difficult to pronounce. The way words are pronounced indicates to a native speaker whether they’re talking to a second-language speaker.
Dutch is a Melting Pot of Languages
Just as English owes a lot to Dutch for contributing to its vocabulary, Dutch owes the same to other languages. It picked up words like jus d’orange (orange juice) and pantalon from French, mazzel (lucky) and tof (cool) from Hebrew and others. Dutch also incorporates texting and social media slang from English as well as street slang from places like Morocco, the Antilles, and Suriname.
