Adding to Anderlc's answer, a less violent situation is when someone is pouring you a drink and you want to tell them they have poured enough, you can say "Chega!". So even though the hint is accurate, I agree it really should have mentioned that "chega" can mean "arrive(s)".
Well, sometimes, it does. You know when someone is insulting you and you say something like "Enough!" or two people are fighting and you say just the same thing or any other case like that? Well, in these cases, in Portuguese, you'd say "Chega!" (or "Já chega!" "Basta!" or something like that).
How would I say that he arrives in xxx (city or country) in June? This way I could better remember "chegar" as "arrive" :-)
Ele chega a _ em junho.
Actually, you should use "chegar a" (according to grammar rules), but everybody uses "chegar em" (as in "Preciso chegar logo em cassa") Maybe they change it officially one day =)
I had this on a listening exercise. Junho didn't sound right. I've reported. Sounded like Juena, which I'm not sure is a word but that's what it sounded like. Reported.
