Origin and History

The phrase “up on” likely evolved from the broader usage of “up” to indicate advancement, progress, or elevation in various contexts. Over time, it came to be used colloquially to denote being informed or knowledgeable about something. While it’s difficult to pinpoint an exact origin, the usage of “up” in English to signify a state of heightened awareness or knowledge dates back centuries.

The earliest printed record of the phrase “up on” can be found in the book “The Pilgrim’s Progress” by John Bunyan, published in 1678. It reads:

“They asked him, Whence he was, and whither he was bound? He said, That he was a Pilgrim, going to the Celestial City, but was not quite up on his Journey yet.”
