Origin and history of ejulation

"wail; cry of sadness or lamentation," 1570s, from Latin ejulationem (nominative ejulatio), "wailing, lamentation," noun of action or state from past-participle stem of ejulare "to wail, lament," which is perhaps from heu, ei, exclamation of grief or fear, from Proto-Italic *iu, a cry of surprise. Compare jubilation.

Herein lyeth a maine difference betwixt mens estates here and hereafter. Hereafter in Heauen is nothing but matter of gratulation: in Hell is nothing but matter of exclamation and ejulation. On Earth there is a mixture of both. [William Gouge, The Saints Sacrifice, 1632]
