migratio

Migratio is a Latin noun meaning migration or moving from one place to another. It derives from the verb migrare, “to move.” In classical and medieval Latin texts, migratio is used to describe human or animal movement, changes of residence, and the spread of populations, trade, or ideas. The term appears in legal, ethnographic, and geographic writings to discuss the process or result of relocation.

In scholarly Latin, migratio often functions as a broad term for various migratory phenomena, ranging from seasonal animal movement to large-scale population displacements. When Latin authors discuss modern phenomena, they typically render the English term migration with migratio or use circumlocutions to describe movement.

Related terms include emigratio (emigration) and immigratio (immigration), which specify departure from and arrival in a homeland, respectively. The term migratio is thus distinct from these more specific forms but can be used to address movement in a general sense.

In contemporary usage, migratio is encountered mainly in historical texts, linguistic studies, and discussions of Latin vocabulary and philology. It is not a technical term in modern biology or social science, where the modern English word migration or language-specific translations are preferred. The concept remains central to understanding discussions of movement across space—whether of peoples, animals, or ideas—in historical sources and in the study of Latin language and medieval scholarship.
