What does homogeneous mean?

Homogeneous most generally means consisting of parts or elements that are all the same. Something that is homogeneous is uniform in nature or character throughout.

Homogeneous can also be used to describe multiple things that are all essentially alike or of the same kind.

In the context of chemistry, homogeneous is used to describe a mixture that is uniform in structure or composition. The verb homogenize means to make something homogeneous. To homogenize milk is to blend it in a way that results in the milk fat being evenly distributed throughout it. The state of being homogeneous is homogeneity.

The general sense of homogeneous can be used interchangeably with the word homogenous (which is spelled without a second e and is pronounced differently). When used in this general way, homogenous is more commonly used than homogeneous. Homogenous is also used in the context of biology to mean corresponding in structure due to either a common origin or a common environment.

The opposite of most senses of homogeneous is heterogeneous, which most generally means consisting of different, distinguishable parts or elements.

Example: This suburb is so homogeneous—even the houses all look the same.

Where does homogeneous come from?

The first records of the word homogeneous come from around 1640. It comes from the Greek homogenḗs, meaning “of the same kind,” from homo-, “same,” and génos, “kind.”

In every context in which it’s used, homogeneous is used to describe things that are essentially alike or uniform throughout—without any or much variation. The word homogeneous may sound a bit more technical than homogenous and it usually is. In chemistry, homogeneous mixtures are those whose parts are evenly mixed. In math, homogeneous is used to describe things like equations that have similar elements or common properties. In sociology, a society that has little diversity is considered homogeneous.

When used generally, homogeneous is often associated with things that are considered biased, boring, or bland due to being all the same.
