Entrain

To cause or allow something, typically a substance or process, to be carried along or caught up within another. This can refer to the incorporation of a smaller element into a larger one, like particles in a fluid, or more abstractly, the inclusion of a group or individual into a larger structure or system. The term emphasizes a process of being drawn in or assimilated, often implying a continuous or ongoing interaction. In a more technical sense, entrainment describes synchronization or alignment, where one element assumes the characteristics or pace of another. The process can also signify the act of preparing or equipping for a specific purpose, especially travel. The core concept of entrainment focuses on the relationship of inclusion, being absorbed, and adaptation.
