The word "uma" means "a" in English, but it also means "one". Although using "He drinks one cup of coffee" is wrong? Why?
If you say that,I think it implies that he drinks only one. It's correct, but the meaning can change wether you choose to translate it with "one" or "a". In general, it's better to choose "one" only when the context need it.
I received an accent prompt for xicara.... where is the accent, over the i?
xicara is purely brazilian portuguese, though now understood in other portuguese speaking zones, last time checed xicara is for a small cup
Chávena in Portugal. :)
Technically, a cup of coffee in Portugal is actually a cup (shot) of espresso in the US.
But xícara is old Portuguese that fell into disuse last century in Portugal, and comes from Castilian (Spanish) via the Aztecs while chávena comes from Malay via the Chinese.
I made a typo and wrote "He drinks a cup of coffe" and I got it wrong. Why??
You might have a typo in your answer cause I put that and it was right. It's ''he drinks a cup of coffee''
In the US, a xícara of coffee is traditionally served at home in a ceramic cup as opposed to a glass cup. Therefore we to differentiate a xícara from a copo we call it a "mug." You still would ask for a cup of coffee, but mug is a slang term for a ceramic cup as opposed to a paper cup.
Except mug in Portuguese is different, caneca.
Xicara is a cup, and in Portugal at least it is quite small, espresso coffee size often (when used for coffee). Chávena actually has the root of Chá in it so is more a teacup (in the English mind though used for all sorts of hot beverages in Portugal). Both are usually ceramic or porcelain. Copo is more a glass (without handle), though some cups are indeed made with glass (making them clear) .
I do not think mug is a slang term in English.
But it would be odd indeed to be served coffee in a mug anywhere but at home (where tea often gets the mug treatment too):
Another difference is that in English a cup is also a measurement (8 ounces) while a mug is usually 12 ounces, or even more. Cups in Portugal tend to be smaller though.
Not everything translated to English from a phrase using, "of" (de in Portuguese) will become a possessive (o gato dele/his cat). English uses many "of" phrases such as, "cup of coffee" and "United States of America" rather than America's United States. :)
I do not know why people voted you down though. People asking questions here should not be discouraged like this. It is exactly what the discussions are for here. :(
