IPA: /ɪnˈtreɪn.mənt/
KK: /ɪnˈtreɪn.mənt/
A process where a solid or liquid is moved or mixed by a fluid, often seen in natural phenomena like rivers or boiling liquids.
The entrainment of sediment in the river changed the landscape over time.
Entrainment is formed from "en-" (meaning to cause to be in) and "train" (from Old French *traïner*, meaning to pull or drag). The word describes the process of causing something to be pulled along or synchronized with another system.
Think of 'causing to be in' ('en-') and 'pulling' ('train') together, which helps you remember that entrainment means synchronizing or pulling something along with another.
