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?


Yes, we don’t know the rules to conjugations, we just know them. But you know what’s faster than that? Not having that to begin with.
In Spanish we also have lots of words that sound the same but mean different things, for example Punto means dot, point, spot, stitch, stop (in the meantime of bus stop). Plus, I would argue that’s not a problem when you’re learning the language, in fact the opposite is true, having many words to mean the same thing makes it hard to learn since the same thing can be said in a multitude of ways, and it might be because English is not my first language, but I find Spanish to have lots more synonyms or entirety different ways of saying the same thing.
