[Star Wars] How can different races understand each other without speaking the same language?

So I'm rewatching a New Hope and I'm noticing some stuff. Luke's Uncle manages to barter with the hooded dudes, (Jawas?) without speaking the same language. They don't speak English, he doesn't speak whatever the heck they're saying. We see the same thing with Han and Chewie. How does that work?

Okay, so imagine two humans. One is German, one is French. 

The German speaks German and French. The Frenchman speaks French and German. 

The German says something in German, and the Frenchman replies in French. 

They both understand each other, despite speaking two completely different languages.
