What's the "een" in Halloween?
early 13c., "represent in painting or drawing, portray;" early 14c., "paint the surface of, color, stain;" from Old French peintier "to paint," from peint, past participle of peindre "to paint," from Latin pingere "to paint, represent in a picture, stain; embroider, tattoo," from PIE root *peig-/*peik- "to cut" (cf. Sanskrit pimsati "hews out, cuts, carves, adorns," Old Church Slavonic pila "file, saw," Lithuanian pela "file"). Sense evolution between PIE and Latin was, presumably, from "decorate with cut marks" to "decorate" to "decorate with color." Cf. Sanskrit pingah "reddish," pesalah "adorned, decorated, lovely," Old Church Slavonic pegu "variegated;" Greek poikilos "variegated;" Old High German fehjan "to adorn;" Old Church Slavonic pisati, Lithuanian piesiu "to write." Probably also representing the "cutting" branch of the family is Old English feol (see file (n.)).

Jezebel "painted her face" (2 Kings 9:30); and the practice of painting the face and the eyes seems to have been common (Jer. 4:30; Ezek. 23:40). An allusion to this practice is found in the name of Job's daughter (42:14) Kerenhappuch (q.v.). Paintings in the modern sense of the word were unknown to the ancient Jews.
