peregrinus

Latin peregrinus meant 'foreigner' or 'stranger'—from per ager, 'through the fields,' describing someone who traveled through the countryside. In Roman law, a peregrinus was a non-citizen, someone from beyond the borders. The word carried no religious meaning at all—just the simple fact of being far from home.

Early Christianity transformed the word. Church Latin used peregrinus for believers who journeyed to holy sites—Rome, Jerusalem, Santiago de Compostela. The foreigner became the faithful traveler. The legal term became a spiritual one. Through Old French pelerin, the word evolved into the English pilgrim by the 1200s.

The Pilgrims—capital P—who sailed to Plymouth in 1620 didn't call themselves that initially. William Bradford used the word 'pilgrimes' in his journal, and the name stuck retroactively. A word that meant 'Roman foreigner' was now defining the founding mythology of a nation.

Today, pilgrim carries both the religious and the secular—pilgrimage to Mecca, pilgrimage to Graceland, the Pilgrim Fathers. But the oldest meaning still resonates: a pilgrim is fundamentally someone who is not where they belong, moving through unfamiliar fields toward something they hope is there.
