The phrase "gain on" is composed of two words: "gain" and "on".
The word "gain" has its roots in the Old Norse term "gegn", which means "straight", "direct", or "against". Over time, this term evolved and was borrowed into Old English as "gegn", often used with the sense of "advantage" or "progress". In Middle English, it developed further into "gain", which came to mean "increase" or "profit".
The preposition "on" originates from Old English, where it was spelled as "an" and meant "in", "into", or "upon". It is derived from the Proto-Germanic word "ana", which carries a similar meaning. Throughout history, "on" has been used to indicate movement or proximity.
