And easy to imagine that it would help mutual understanding and communication immensely. It's harder to hate people you can make connections with.

Coming back to mz's initial take, though, I also often think about this. Just the idea of being able to communicate with everyone in a language you're fluent in, no matter where you are in the world is so sexy.

And we haven't even talked about languages with dual as third grammatical number

That is kinda what I'm talking about. Like I wouldn't be able to explain how pluralization works other than instinctively knowing what's the right plural for each case by case word. English slapping an "s" at the end is a breeze.

Not by name, that's for sure ^^

Ah, "only" 5. Still. To a German brain, that's one too many ^^
