on

on: [OE] On is an ancient Germanic preposition, with relatives in German (an), Dutch (aan), and Swedish (?), and also connections outside Germanic (such as Greek aná ‘on’ and Russian na ‘on’)

on (prep.)

Old English on, unstressed variant of an "in, on, into," from Proto-Germanic *ana "on" (cognates: Dutch aan, German an, Gothic ana "on, upon"), from PIE root *an- "on" (cognates: Avestan ana "on," Greek ana "on, upon," Latin an-, Old Church Slavonic na, Lithuanian nuo "down from"). Also used in Old English in many places where we would now use in. From 16c.-18c. (and still in northern England dialect) often reduced to o'. Phrase on to "aware" is from 1877. On time is from 1890.
