Forms

mīrāculōsus (feminine mīrāculōsa, neuter mīrāculōsum); first/second-declension adjective[1][2]

Etymology

It is formed from Latin mīrāculum + -ōsus.[3] The noun mīrāculum (“wonder, marvel”) comes from mīror (“to wonder at”),[1] which belongs with mīrus (“wonderful”); de Vaan traces that to Proto-Italic *smeiro- and Proto-Indo-European *sméi-ro- (“laughter”).[4]

Earliest recorded meaning

Köbler's earliest source is the Summa theologiae of Thomas Aquinas (1265–1273), where it means miraculous.[1][5]

Semantic evolution

In British Medieval Latin it meant remarkable or wondrous, and also miraculous as opposed to natural: John Blund says the resurrection of the dead will be not natural but miraculosa.[6] It could also describe something that works wonders.[6] Thomas Aquinas speaks of a miraculous act, conception, conversion and change.[5]

It was used in the Medieval Latin of Hungary, Bohemia and Poland,[2][7][8] as in Simon of Kéza's miraculosum praelium, the wondrous battle that King Ladislaus fought against the Cumans.[2]
