In contact with and supported by a surface; happening or operating; or continuing.
From Old English "on" meaning "in, into, on, onto," related to German "an." Over time, English split its older "on/in" meanings into separate words like "on" and "in."
This tiny word does a lot of work: a light is "on," a show is "on," and your mind can be "on" something. It’s like a Swiss Army knife of connection, always gluing actions to surfaces, times, and topics.
