The phrase "brighten up" is a combination of two words: "brighten" and "up".
The word "brighten" is derived from the Old English word "bryhtan", which means "to become bright or shining". It is related to the Middle Low German word "brehten" and the Middle Dutch word "brechten". These words, in turn, ultimately trace back to the Proto-Germanic word "berhtijaną", meaning "to make bright".
The word "up" is a simple adverbial particle that intensifies the meaning of "brighten". "Up" has Old English roots and comes from the Old English word "ūp", which has a similar meaning to its present-day usage.
Therefore, when combined, "brighten up" means to become or make something brighter or shinier.
