Aspersion (la. aspergere/aspersio), in a religious context, is the act of sprinkling with water, especially holy water. Aspersion is a method used in baptism as an alternative to immersion or affusion. The word is formed of the Latin aspergere, 'to sprinkle', of ad, 'to', and spargo, 'I scatter' (Ezekiel 36:25-26, 1 Corinthians 10:2, cf. Psalm 77:16-20). In addition, aspersion is performed as part of certain rites to remind people of their baptism, such as the renewal of baptismal vows performed by the Roman Catholic Church on Easter.
