Bye-gones

Bye-gones refers to things that are past or gone; past events or times. It suggests a sense of something that is over and done with, often implying nostalgia, regret, or a conscious decision to move on. The term is frequently used in the phrase "let bygones be bygones," which encourages forgiveness and a willingness to forget past offenses or disagreements to achieve reconciliation.

The word "bye" in this context is an archaic form meaning "past" or "over." Thus, "bye-gones" literally translates to "past things" or "gone things."

The concept is often associated with the idea of not dwelling on the past and focusing on the present or future. It can also imply a separation from outdated customs, traditions, or practices. The term can have a slightly melancholic tone, acknowledging the passage of time and the irretrievability of what has been lost.
