Borrowed from Latin ululātiō, from ululō (“to howl, shriek, yell”) (from a reduplicated Proto-Indo-European imitative root) + -ātiō (suffix forming nouns relating to some action or the result of an action) (from Proto-Indo-European *-tis (suffix forming abstract or action nouns from verb roots)). By surface analysis, ululate + -ion.
ululation (plural ululations)
