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.


I remember learning Spanish in school. Discovering the difference between “dejar” and “irse” drove this home for me. Dejar - to leave [a thing somewhere.] Irse - to leave [a place.] (“Salir” also works for the latter meaning, but it can mean more of “to go out.”)
“Ella se fue y dejó el libro en la mesa.” (“She left and left the book on the table.”)
Speaking of “driving (a point) home,” I’d say one of the weirdest/most interesting quirks of English is how many idioms we rely on.
