treater

One buying rounds

A treater is someone who treats—whether treating guests to dinner, treating patients for illness, or treating materials with chemicals.

The word appears most often in industrial contexts: The water treater maintains the cooling system.

In casual use, it often means someone who pays for others: She's always the treater when we go out.
