Etymology: From Middle English greter, gretter, equivalent to greet + -er.

1. A person who greets people on their arrival.

   “The greeter is standing most or all of the time, and the weather may be unpleasant at that time of the year. If the greeter can bring a folding chair to sit on in slow periods, so much the better.”

2. A volunteer who shows tourists around their home city or region for free.

   “Visitors are matched with a volunteer Greeter according to shared interests and languages spoken, and their 3-4 hours together is a combination of what the Greeter has to offer and the visitor wants to know.”
