Is it the definite article?
So, to reiterate, when it comes to when to use the “the”, the only universal rule is this:
Some rules (such as the two you’ve given) might hold 95%+ of the time, but unfortunately there may be weird and arbitrary exceptions that you’ll just have to learn.
Is it capitalization?
Because a cursory look at the Wikipedia page for capitalization also reveals that it is not without its quirks.
For example:
planets and other celestial bodies: “Jupiter”, “the Crab Nebula”; and “the Earth”, “the Sun”, or “the Moon” should be capitalized according to the International Astronomical Union based on its manual of style, but style guides may suggest differently.[19]

Is it the fact the way something is written almost has no bearing on how it’s pronounced?
Please tell me your thoughts.


IMO, the weirdest thing about English is something every speaker does but probably never thinks about.
Whenever multiple adjectives describe a single noun, there’s a particular order in which they must go. If you have big tractor that’s also green, you would call it a “big green tractor” but you would never call it a “green big tractor”. Not only does it sound wrong, it’s grammatically incorrect.

100% this. No one is ever taught it as a rule in school. You’re never tested over it. But all native English speakers intuitively know it.
