fútbol vs futbol
Duolingo shows both spellings but do they both refer to the same game? Is one what I, as a U.S. resident, would think of as Football and the other Soccer? If they are the same game would one spelling be preferred over the other? I tried to search whether this had been discussed before but was unable to get the search function to work.
I've always known the translation of soccer to be "fútbol" (Not a native speaker of spanish btw) and football is "fútbol americano". I don't know about "futbol", without the accent :/
Futbol y fútbol son lo mismo.
If you stick to the rules of Spanish "fútbol" has stress on the "u" whereas "futbol" has the stress on the "o".
