Are There Common Structures to Human Language?

Ven puts aside aliens and intelligence, we wonder what life might look like on other planets. We imagine common structures that are everywhere on earth might be universal to all life. Can we play the same game and think about how alien languages might work based on the diversity or universality of elements of language here on earth? Ven: You can make some speculations based on what we know. What we know is not enormous, but there's fairly solid evidence that it's an essential species property common to humans.
