Usage
What does agglomerate mean? Agglomerate means to collect or gather into a cluster or mass, especially a messy or jumbled one. As a verb, agglomerate is typically used in a passive way (as opposed to someone doing the agglomerating), as in Much of the garbage in the ocean has agglomerated into a giant floating mass. The process of agglomerating is called agglomeration. Agglomeration can also refer to a messy cluster or jumbled collection of various elements. Agglomeration is often used to refer to groupings of miscellaneous things—such as various types of objects or even people—into a single (though often somewhat messy) unit. Agglomerate can also be used as a noun to mean the same thing. The similar word conglomerate can be used in many of the same ways that agglomerate can, but it doesn’t doesn’t always imply a sense of messiness like agglomerate does. And conglomerate is most commonly used as a noun meaning a large corporation consisting of many companies. Agglomerate can also be used as an adjective to describe things gathered together into a jumbled mass, as in My desk has become an agglomerate mess. It can also be used in a few more specific ways. In botany, it’s used as an adjective to describe plant parts that are crowded into a dense cluster but not fully connected. In geology, it’s used as a noun referring to a type of rock composed of volcanic fragments. Example: I forgot that the art project was due today, so my collage is really just an agglomerate of things I found around the house.

Etymology
Origin of agglomerate
1675–85; < Latin agglomerātus (past participle of agglomerāre ), equivalent to ag- ag- + glomer- (stem of glomus ball of yarn) + -ātus -ate 1
Explanation
When things agglomerate, they gather together into a cluster or a group. In some states, people tend to agglomerate into cities, leaving rural areas sparsely populated. You might come across the verb agglomerate in business news — moguls tend to agglomerate companies, collecting them under one controlling interest. You could also describe a website that agglomerates news items, gathering them all into one place. The Latin root word is agglomerare, "to wind or add onto a ball," from ad, "to," and glomerare, "ball of yarn."
