Let's try your favorite "a weather". And if this one is not absolutely uncountable, then I'll personally write a letter to that language purification institution to ask them what's going on with English.

Native speakers make mistakes too. "You must've wrote". I can recall the "he's been gone since Monday" phrase that was absolutely smashed by the same native speakers that are so ardently "liking" every single post that the non-native speakers put up.

You must've wrote is not something that most native speakers would accept as standard.
It's really the essence of Portugal, a music that captures the rhythm and cadence of the ocean waves is something that most native speakers would accept as standard.
If you cannot accept that, Bennevis, there is no point in continuing. I am not going to close the thread, but I am leaving it.
Davao City is typhoon-free. The city enjoys a weather that remains balmy all year round. It is characterized by a uniform distribution of rainfall, temperature, humidity, and air pressure. It has no pronounced wet or dry season.

Good luck with the letter!
OK. Is Herman Melville good enough? (1876)
Peers, peers--yes, needs that these must pair.
Clarel was young. In promise fine,
To him here first were brought together
Exceptional natures, of a weather
Strange as the tropics with strange trees,
Strange birds, strange fishes, skies and seas,
To one who in some meager land
His bread wins by the horny hand.

I agree there is no point in continuing this discussion. The exception proves the rule. And if you guys can't organize your own language and keep lying to students all over the world about what's really going on in real life, then
I'm not really sure that I can see the point in continuing with this. You say English is being mangled. Native speakers say that the language is simply changing or evolving. Many words, phrases and usages change over time. I'm pretty sure that textbooks can't keep up with the actual language. It's the same reason that the native speakers here spend a lot of time advising people as to whether or not something sounds natural in addition to/instead of whether it's correct or not.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
The truth of the matter is that there many more absolutely countable nouns than there aren't. Take any "car" and check its parts. 99% are absolutely countable.
