Human and humane

Sometimes languages are funny. I've found that often one language will have two similar words for two different things, while another will use the same word for both. Today's example: human and humane. These are two different things in English, but the same word in Spanish.

Human is a noun or an adjective. As an adjective, it simply means "related to human beings".

Humane is an adjective only. It most commonly refers to something "characterized by kindness, mercy, or compassion". The Humane Society, for example, has nothing to do with humans, but everything to do with being kind, merciful and compassionate towards animals!

Just to make things a little more confusing, the uncountable noun humanity refers to both of the above meanings!
