means A journey, often long and effortful, made to a sacred place or to somewhere of deep personal significance.

from From the Latin peregrinus, meaning 'foreigner' or 'one from abroad' — built from per ('through') and ager ('field, land'), so literally someone wandering through open country, beyond their own borders. It traveled through Old French pelerin into Middle English as 'pilgrim,' the wanderer who walks far for holy purpose; 'pilgrimage' is simply the journey that wanderer makes.
