Plural of aspergillum; multiple vessels or brushes used for sprinkling holy water in religious ceremonies.
Regular English plural formed by adding '-s' to the Latin singular 'aspergillum.' The word maintains its Latin roots while following English pluralization conventions adopted when the term entered English religious and liturgical vocabulary.
Even in English, we often keep Latin plurals or create hybrid plurals—you might hear 'aspergilli' (Latin plural) in scientific contexts, but 'aspergillums' follows the more modern English approach of just adding '-s' to borrowed words.
