Usage

What does heterogeneous mean? Heterogeneous most generally means consisting of different, distinguishable parts or elements.The word is used in a more specific way in the context of chemistry to describe a mixture consisting of two or more different substances or the same substance in different phases of matter (such as ice and liquid water).In either sense, the state of being heterogeneous is heterogeneity.The general sense of heterogeneous is not as commonly used as the general sense of its opposite, homogeneous—which most often means consisting of parts or elements that are all the same. The word homogenous (which is spelled without a second e and is pronounced differently) can be used to mean the same thing.The word heterogenous is very similar in spelling but not in meaning. It’s used in the context of biology and medicine to refer to something that originated outside of the body or that is derived from another individual or species (such as a skin graft).Example: The exhibit features a heterogeneous mix of artifacts from different cultures and eras.
