overwrite

Imagine writing a draft of a story, then deciding it is not quite right and typing new words right on top of the old ones. That is what it means to overwrite. Most often, it means to save or write new data onto something that already has data on it, so the older information is replaced. This is common in computing: if you save a file with the same name, the new version may overwrite the old one. It can also be used more generally for replacing one thing with another so fully that the first one is no longer seen or used. Think of painting over an old mural: the new paint hides what was there before. If you do not keep a backup, an overwritten file may be hard or impossible to get back.

To overwrite means to write over existing content, replacing it with something new. It is a term most commonly associated with technology and data storage. When you save a file on your computer, the new information is often written over the old version—effectively deleting the previous one unless you've created a backup. This can happen accidentally (like saving a file without realizing you haven't kept the original) or intentionally (like updating software or wiping a drive).

However, "overwrite" is not limited to computers. It can also be used figuratively to describe situations where one thing replaces another. If a new memory "overwrites" an old one, or if a leader's vision "overwrites" the concerns of their team, the original viewpoint is pushed aside by the new one. While similar to "override" (which means to use authority to cancel something), "overwrite" specifically suggests that the original is being replaced by new information or a new layer.

In some literary contexts, "overwrite" can also describe the act of writing too much or using a style that is overly elaborate and wordy, though this usage is less common today than its technical counterpart.

The key idea behind "overwrite" is replacement. Something that already exists is covered up or erased by something new. It often implies a degree of finality: once something is overwritten, the original information can be difficult or impossible to recover. Whether you are talking about computer files, memories, or plans, to overwrite means to replace what was there before with something new, often with little chance of getting the original back.
