OED analyzes friend as a noun use of the present participle behind the Germanic free and love family, and it explicitly calls fiend a similar formation. Bosworth–Toller makes the Old English structure visible: freónd is the loving participle of freón, to free or love. The enemy word follows a different hate verb. The real unveiling is structural: one inherited agent noun is the loving one, the other the hating one or enemy, and parallel grammar must not be mistaken for one root splitting into moral opposites.

OED and Bosworth–Toller preserve the morphology behind frēond: an inherited nd-stem formation tied to the verb meaning free or love. The same sources then refuse a slogan-sized definition. Old English uses cover close companion, ally or non-enemy, relation, friend of God, friend versus foe, and friends acting as arbitrators. Cotton MS Vitellius A XV folio 152r visibly preserves freondum in a hall filled with favored people at Beowulf 1018. The unveiling is not that friend secretly means love in every sentence; it is that a loving-agent fossil became a socially versatile noun before modern English existed.
