Aspersio

Aspersio is a Latin noun meaning the act or process of sprinkling a liquid, especially water, on someone or something. It derives from the verb aspergere, “to sprinkle,” with the noun-forming suffix -io indicating an action. In ecclesiastical Latin, aspersio denotes the rite of sprinkling holy water, a purification and blessing ritual that is common to Western Christian liturgies.

In liturgical use, the aspersio is typically performed with a sprinkler or aspergillum, by a priest or deacon, and is part of various rites, often conducted during the celebration of the Mass or before worship. The rite is sometimes referred to simply as the Asperges, and the accompanying chant or formula emphasizes cleansing and sanctification. The practice dates to early Christian worship and persists in many denominations, though details vary by tradition.

In scholarly and liturgical texts, aspersio appears as a technical term within descriptions of rites and their elements. It can be contrasted with other forms of sacramental blessing, such as the anointing or benediction. In contemporary usage outside specialized writing, the term is largely encountered in historical or religious contexts, rather than as a common everyday term.

Translational note: Aspersio is Latin; in languages other than Latin, equivalents include terms meaning “sprinkling” or “aspersión/aspersão” depending on language.
