etymonline
wisdom (n.)
Old English wisdom "knowledge, learning, experience," from wis (see wise (adj.)) + -dom. A common Germanic compound (Old Saxon, Old Frisian wisdom, Old Norse visdomr, Old High German wistuom "wisdom," German Weistum "judicial sentence serving as a precedent"). Wisdom teeth so called from 1848 (earlier teeth of wisdom, 1660s), a loan-translation of Latin dentes sapientiae, itself a loan-translation of Greek sophronisteres (used by Hippocrates, from sophron "prudent, self-controlled"), so called because they usually appear ages 17-25, when a person reaches adulthood.
