"By the board" is a nautical phrase that refers to an object or entity being completely destroyed or lost, often as a result of a shipwreck or severe damage. This term originated from the practice of placing a wooden board with notches alongside a ship to measure the water depth. When a ship hit a shoal or reef, it might strike the board, resulting in it being broken or knocked overboard. Over time, this phrase evolved to describe the destruction of an entire vessel, along with its cargo or crew.
In a more figurative sense, "by the board" can also be used to describe the complete failure or demise of something, such as a plan, project, or business. It implies a total loss or collapse, indicating that the endeavor has been completely abandoned or rendered useless.
Furthermore, "by the board" can also be used colloquially to describe something being put aside or dismissed, usually with a sense of disregard or neglect. It implies that the matter is no longer considered or relevant, as if it has been discarded, similar to throwing an item overboard.
Overall, "by the board" is a term that conveys the concept of complete destruction, failure, abandonment, or dismissal, often originating from nautical contexts but now used figuratively in wider contexts as well.
