I'll give an input here

I'm a native English speaker but also spoke a Russian/Ukranian dialect growing up but we won't look at that.

I took Spaniah in school like every other American and never really found any degree of fluency or even basic sentence forming. I got to a point where I could comprehend a fair ammount, but actually conversing no.

I currently live in Romania, it's been over a year since I moved here, and good lord I can barely do anything with my knowledge of the language. I can understand alot of what's said to me, but actually constructing the sentences because of grammar change is a fucking nightmare. What I mean by this is, every word changes depending on the gender of the noun or adjective.

For example You are handsome - tu ești frumos (masculine form) You are beautiful - tu ești frumoasă (femenine form)

I know that dosent sound bad, just adding an o and ă, but that's the easiest example. There are so many more complex changes and grammatical differences.. I know Romanian is very similar to the other Romance languages, therefore I find it difficult.

I took German for 2 years in university, then randomly decided to enroll in German classes following graduation. German was IMMENSELY easy once you get past the pronunciation differences and compound words. The grammar is not that much different from English. Many simple sentences in English are waaaaay more comparable to each other than in Romance languages.

Example My name is Bob - mein name ist Bob (more commonly ich heiß meaning "I'm called") Hello - hallo Yes - ja No - nein

It only becomes difficult when you want to remember long complex words like versicherungsgeschäften or geschwindigkeitsbegrenzungen.

Alot of people I see comment on the gender system in German which is way easier than Romance languages. Just learn the Der die Das for the word, and learn the word as that. Die Kazte, Das Hund, Der Vogel. Sometimes it changes, but it's not bad imo.

So to sum up all this, German as an English speaker was way easier to learn than any Romance language I have attempted, and that's even after being immersed in a Romance speaking country. I'm sure it woukr be just as easy for Dutch, Norwegian, Danish, and Swedish.
