"I am a man."
Translation:Jag är en man.
Even though it means the same it doesn't work well for introductions. "Jag heter Marcy" (My name is Marcy) or "Hej. Marcy." while shaking hands and making eye contact works when you first introduce yourself. If you are meeting someone who are expecting you but you haven't meet before then "Hej. Det är jag som är Macy." Simular but more polite.
I'm not sure BUT maybe it's like the german "man" which, translated would mean something like "it is verb in past participle" or, in Spanish, a pasive voice using "se" Ex.: German: Man trinkt Spanish: Se bebe / Uno bebe English: It is drunk -meaning that you don't eat it, you drink it- / One drinks (it) / You drink (it)
Btw, I don't really know English or German so.. Sorry about, mostly, the grammar mistakes xD
