gargoyle: [15] The ancient root *garg-, *gurgoriginated as an imitation of throat sounds. From it were derived such guttural words as Greek gargaraaizein ‘gargle’ (whence Latin gargarizāre ‘gargle’) and Latin gurguliō ‘gullet’ (Latin gurges, source of English gorge and regurgitate, had moved further figuratively to ‘whirlpool’).
Among the offspring of gurguliō are Vulgar Latin *gurguliāre, source of English gurgle [16], and Old French gargouille ‘throat’. Roof spouts carved in the shape of grotesque creatures had the term gargouille applied to them from the notion that the rain-water was coming out of their throats – hence English gargoyle. Gargouille also formed the basis of the verb gargouiller ‘gargle, gurgle’, from which English gets gargle [16]. => gargle, gurgle
