What's the "een" in Halloween?
mid-15c., from Latin eulogium, from Greek eulogia "praise; good or fine language," from eu "well" (see eu-) + -logia "speaking" (see -logy). Eu legein meant "speak well of."
Words of praise, often for a dead person, but also a staple in introducing speakers, in nominating candidates, and on other such occasions. (Compare elegy.)
