When "gegenüber" is used as a preposition, with a noun, it's "across from" that noun. When it's used by itself, as an adverb, the implication is often "across the street."
In this particular sentence, we probably do mean "across the street from," but the literal translation is just "across from."
I am not sure is the translation offered by Duolingo is the most suitable one, since "gegenüber" could only be translated as "across" in an American context. Here an extract of the online Cambridge dictionary:
"We use across as a preposition (prep) and an adverb (adv). Across means on the other side of something, or from one side to the other of something which has sides or limits such as a city, road or river. [...] Especially in American English, across from is used to refer to people or objects being ‘opposite’ or ‘on the other side’:
The pharmacy is across from the Town Hall"
The official meaning of the word "gegenüber", according to the native German dictionary DUDEN, is:
"gegenüber --> bezeichnet eine frontal entgegengesetzte Lage Grammatik: räumlich Beispiele gegenüber dem Rathaus/(auch:) dem Rathaus gegenüber steht die Kirche"
Therefore there are two possible translations: 1. Opposite as a preposition means ‘in a position facing someone or something but on the other side’:
Jake sat opposite Claire in the restaurant. (Jake and Claire are facing each other on different sides of the table.)
Not: Jake sat in front of Claire …
- In front of as a preposition means ‘close to the front of something or someone’:
There was a woman in front of me in the bus queue who was crying. (I was standing behind the woman.)
So depending on the context, on where exactly "gegenüber dieser Bäckerei" is, we could say opposite or in front of, meiner Meinung nach...
See the 3rd meaning. I'm not saying it is the best translation, but in some content it could be translated like that. Anyway.... no need for such a rebuff.
If I put " opposite this bakery" it is rejected so I changed it to the American answer " across the street from this bakery ", and now that is rejected as well. So now " opposite" has been changed to "across from " and "the street " has been omitted. Wonder what the answer will be next time.
