Yo corro los jueves
what I would like to know is when did los replace sobre for the word on. Last time I checked los is plural for the word "the" not for the word "on". Can someone please explain to me the difference between the two words. Thanks
Sobre means on top of. It can also mean about. In Spanish you don't run "on" Thursdays, you run "the" Thursdays.
The Spanish custom seems to be to put an article before a day of the week, and since jueves is plural the article here is also plural.
We would say "I run Tuesdays", and in Spanish the literal translation is "I run the Tuesdays".
Great question! I'm sure you've realized that two languages don't always match up. "Los" does mean "the", but in Spanish they use "the" in this situation. By the way, "el jueves" means "on Thursday" as in one specific Thursday. "Los jueves" is used when you mean "on Thursdays" as in every Thursday.
