Peregrinus is a Late Latin name, originating as a cognomen meaning "traveller" or "foreigner" (from Latin peregrīnus). In medieval Latin contexts, it was used as a masculine given name and is the Latin base form of Peregrine, which became more common in English-speaking regions.EtymologyThe Latin root peregrīnus derives from peregrē ("abroad") and ager ("field, land"), literally meaning "from beyond the fields." In ancient Rome, peregrinus referred to a non-citizen—someone coming from a foreign territory. The use as a personal name likely stems from its association with early Christian saints who were "pilgrims" spreading the faith.Historical ContextThe name Peregrinus was borne by several Christian martyrs and early saints, including Peregrinus of Auxerre and Peregrinus of Terni. Their veneration made the name common in medieval Christian Europe, especially among Latin-literate clergy. In medieval records, it appears in various Latin documents across Continental Europe. Through vernacular translations, it evolved into the Italian Pellegrino and the English Peregrine, the latter also influenced by the bird name (falco peregrinus), which itself was named for its "wandering" habits.Distinction from PeregrineWhile Peregrinus is the direct Latin form, English Peregrine adapts it to a more Anglicized spelling. In onomastics, Peregrinus is considered the original, classical version, whereas Peregrine appears as a separate later development.Key FactsMeaning: "traveller" or "foreigner"Origin: Latin word converted to a cognomen/given nameType: Masculine first nameUsage Regions: Medieval Latin documents; early Christian ecclesiastical contexts.
