Other forms: touring; toured
Use the noun tour to describe a route taken while sight-seeing or the act of experiencing a place, like a tour of Italy in which travelers tour museums and churches.
Not all tours have to do with vacations. In fact, a tour can be quite the opposite, such as a snowplow driver whose tour during a blizzard lasts until the streets are clear, or military personnel who serve a tour of duty in the place they are assigned. These kinds of tours involve a commitment of work or service for a certain period of time.
