If you went backpacking through Europe last summer, you could call your travels a peregrination. A peregrination is a long journey or period of wandering.
Peregrination comes from the Latin peregrinari, which means “to travel abroad.” A peregrination is a journey or pilgrimage, especially one that's made on foot. This word typically applies to traveling for an extended period of time or over a great distance. So, you wouldn’t call a trip to the grocery store a peregrination. However, if you traveled the globe looking for the world’s best grocery store, you could call that a peregrination.
