Like, English is a famously difficult language, and Spanish is supposed to be easier. But babies learn English or any language instinctually.
So do babies learn faster if the native language is easier, or do they acquire language at a constant rate depending on their brain development or whatever?


I can’t speak to Spanish, but in English and French anyway, there are many ways to say almost the same thing, but they all have slight variations and nuances and meaning. That’s why poetry is so fun.
Yes, that’s the same with most languages. My point is that being proficient in several languages I find English text a lot more repetitive, whereas Spanish text has multiple turns of phrases used to avoid repetition, which also makes it a lot harder to learn (although I don’t think we expect kids to know many synonyms for stuff, and children books tend to stick to simpler construction of phrases).
The things I’ve seen people point to English to claim it’s hard are not really needed to be fluent in speaking the language (which is what kids do).
