An excessive flow of saliva.
Hypersalivation can occur during certain medical conditions or as a side effect of some medications.
Hypersalivation is formed from "hyper-" (meaning excessive) and "salivation" (from Latin "salivatio", meaning the act of producing saliva). The word describes the condition of producing an excessive amount of saliva.
Think of 'hyper-' meaning excessive, and 'salivation' referring to the act of producing saliva. This helps you remember that hypersalivation means an excessive production of saliva.
