Translation:He is drinking beer, because he is unhappy.
Potentially stupid question: "he drinks beer because he is sad" and "he is drinking beer because he is sad" are both accepted answers. However, as a native English speaker I infer different things about the man from the tense/aspect combination: first, he's a depressed alcoholic; second: he's had a bad day. Does Esperanto have a mechanism to make this distinction or is it all about context?
Mi profitas la okazon por fari kelkajn rimarkojn, ĉu bone?
li estas malfeliĉa ĉar li havis malbonan tagon; li drinkas ĉar li estas malfeliĉa;
li estas malfeliĉa ĉar lia kato forpasis antaŭ 10 jaroj en stranga kuirej-akcidento; li drinkas ĉar li estas (ankaŭ) malfeliĉa.
Context, I guess. It is possible that someone decides on a beer, rather than a lemonade or a water of life, for being unhappy. But what we read more often is that people are drinking (beer) because they're unhappy.
They both seem fine to me. If someone finds this is still not accepted, then it could be reported as a correct answer.
In Esperanto, every noun ends with an -o, the -n gets placed at the end of a word if it's accusative. I recommend to take a look at the duolingo website (also accessible on the phone), you can find tips and explenations about the grammar there when clicking on the little light bulb. You don't have this function when you use the app. I hope this helped
Defeatist phrases should be avoided, as they are useless. Insulting phrases, such as "We don't need such idiots here", or insistent phrases on the subject of alcoholism, should also be avoided. Positive, constructive and uplifting phrases are welcome, as they help to improve the mood.
I just thought I'd mention - at the risk of being taken the wrong way - that "funny" comments can be annoying to some of the people who are searching the forum for unanswered questions. "Funny" comments means more notifications and more threads to sort through to find people who are looking for help.
I see that ionasky has brought this to your attention. I didn't say anything on that thread. If you're level 25, maybe you could start answering some basic questions at this point. There are tons of questions like "why is it 'la angla' and not just 'angla'?"
I'm sure it would be appreciated.
Salivanto, I like to joke, and I intend to continue (free Internet and stuf - hope you don't take it the wrong way either) BUT I do accept criticism the right way. I confess that I did not unsderstand ionasky's "hint" (had to look up the comment again) and now that I realise that I had not answered a question in quite some time, I apologize and promess I will be more attentive to it.
Thanks for the straight talk.
