Origin & History of “free”

The prehistoric ancestor of free was a term of affection uniting the members of a family in a common bond, and implicitly excluding their servants or slaves – those who were not ‘free’. It comes ultimately from Indo-European *prijos, whose signification ‘dear, beloved’ is revealed in such collateral descendants as Sanskrit priyás ‘dear’, Russian prijatel’ ‘friend’, and indeed English friend. Its Germanic offspring, *frijaz, displays the shift from ‘affection’ to ‘liberty’, as shown in German frei, Dutch vrij, Swedish and Danish fri, and English free. Welsh rhydd ‘free’ comes from the same Indo-European source.
