IPA: /səˈlɪveɪtə/
KK: /səˈlɪvəˌtɔr/
A substance or agent that stimulates the production of saliva in the mouth.
The dentist used a salivator to help keep the patient's mouth moist during the procedure.
Salivator is formed from "saliva" (from Latin "saliva", meaning spittle or saliva) and "-tor" (a suffix used in Latin to indicate an agent or doer). The word "salivator" refers to one who produces or secretes saliva.
Think of 'saliva' as the fluid produced in the mouth, and the '-tor' indicates someone who does something, so a salivator is someone who produces saliva.
