frig

Etymology 1

From Middle English friggen (“to quiver”), perhaps from Old English *frygian (“to rub, caress”), related to Old English frēogan, frīgan (“to love, release, embrace, caress”), frīge (pl., “love”). More at free. Alternative etymology derives frig (Early Modern English frigge) from Middle English frikien (“to keep (the arms and hands) in constant motion”), from Old English frician (“to dance”).
