harpy

From Middle French harpie, from Latin harpyia, from Ancient Greek ἅρπυιᾰ (hárpuiă), literally "snatcher", from ἁρπάζω (harpázō, "to snatch, seize"). Middle English had the form arpie.

The word traveled from Greek through Latin and Middle French into Middle English as arpie before settling into its current spelling and sense.

It's related to English rapacious, both tracing back to the same root sense of grasping or seizing.
