The term agglomeration can be used both as a noun and as a verb. Dictionary entries of agglomeration as a noun will typically refer to a ''collection or mass of things rudely or loosely thrown or huddled together,'' an ''unmethodical assemblage,'' a ''confused or jumbled mass,'' or merely a ''clustering or cluster.'' As a verb, consequently, agglomeration refers to the act or process of collecting in a mass, of heaping together, or to combine mechanically without any adaptation of parts.
