Word History

Etymology

slipper entry 1 + -y entry 1

Note: As the earliest occurrence of slippery appears to be in the Coverdale Bible (1535, Psalm 35:6), it has been suggested that the addition of the suffix -y to the adjective slipper copies German schlipfferig in Luther's translation of the same passage (1534, present-day German schlüpfrig). The German word is ultimately from the same Germanic base as slip entry 5 (see Oxford Dictionary of English Etymology).

First Known Use

circa 1500, in the meaning defined at sense 1a
