Forms
francus (feminine franca, neuter francum); first/second-declension adjective[1]
Etymology
It is borrowed from Frankish *Frankō (“a Frank”), from Proto-Germanic *frankô (“javelin”).[1] Köbler connects it instead with *frankaz (“bold, free”), for which Pokorny's roots are only tentatively proposed.[2] Compare Old High German Franko (“a Frank”) and Old English franca (“spear, javelin”).[1]
The sense “free” is a generalisation of the people's name: Etymonline explains that the Franks, as the conquering class, alone had the full status of freemen.[3] Niermeyer notes that in medieval documents the name of the nation and the legal status often cannot be told apart.[4] Through Old French franc it is the source of English frank.[3]
Earliest recorded meaning
Köbler finds the noun first in the panegyrics of Eumenius (264–c. 312 AD),[2] where the singular Francus stands collectively for “the Frank”, the Frankish people;[5] the plural Francī “the Franks” is used by Claudian and Vopiscus.[5]
Semantic evolution
As an adjective, “Frankish”, it appears in Jerome's Life of Hilarion, of the Frankish language.[5][6][2] The land of the Franks is Francia.[5] In Medieval Latin the adjective came to mean “French”,[1] and above all “free”: personally free, not servile, and then, of a dependant, exempt from certain manorial dues and services, privileged.[4][7][2] As a noun francus is a freeman or such a privileged dependant,[4][7] and, in a forged diploma of the 12th century, a coin, the “franc”.[7][2][1] British writers use the noun for the Franks, the inhabitants of Francia, and the Normans and Anglo-Normans.[8]
