The closer a language is to yours, the easier it is to understand, the further it is from you, the harder it is to understand. But there's a sort of uncanny valley right in the middle that makes a language sound silly.
I'm an English speaker. German sounds similar, I can even find cognates sometimes. Mandarin Chinese sounds completely alien, but I can understand that it is a language.
But Dutch, Dutch sounds hilarious. Dutch sounds like a clown version of English. I wonder why that is.
I've heard Spanish speakers say similar things about Portuguese, which makes me think there's some sort of linguistic Silly Zone.
I do like that this pandemic has got us all greeting each other like Jane Austen characters- “You are well, I hope? And your family? All in good health?”
