Old English missan "fail to hit, miss (a mark); fail in what was aimed at; escape (someone's notice)," from Proto-Germanic *missjan "to go wrong" (source also of Old Frisian missa, Middle Dutch, Dutch missen, German missen "to miss, fail"), from *missa- "in a changed manner," hence "abnormally, wrongly," from PIE root *mei- (1) "to change, go, move." Reinforced or influenced by cognate Old Norse missa "to miss, to lack." Related: Missed; missing.
