Usage

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.

Etymology

Origin of homogeneous

First recorded in 1635–45; from Medieval Latin homogeneus, from homogene-, stem of Greek homogenḗs “of the same kind” ( see homo-, gene) + -us -ous

Explanation

If a group of things are homogeneous, they're all the same or similar, like a room full of identically dressed Elvis impersonators. The adjective homogeneous comes from the Greek homogenes, meaning “of the same kind.” You can break down the root of the word further into two parts: homos, meaning “same,” and genos, meaning “kind, gender, race, stock.” It sounds very scientific, but if you look around the table at home and everyone is eating a bowl of oatmeal, you could safely describe your family’s breakfast tastes as homogeneous.
