saturate: [16] Latin satur meant ‘full’, and in particular ‘full of food, full up’ (it was a relative of satis ‘enough’, source of English satiate and satisfy). From it was formed a verb saturāre ‘fill, glut, surfeit’, whose past participle has given English saturate. At first this was used as a synonym of satisfy or satiate (‘so to saturate their insatiable hunger’, Thomas Bell, Survey of Popery 1596), and the modern sense ‘soak’ did not emerge fully until the mid 18th century.
