Unselect and deselect both mean to remove a selection. Deselect is the standard and most widely accepted term in software, while unselect appears in some applications but is much less common.
A few years ago, I was reviewing a software guide before it went live. Everything looked great until I noticed one instruction: “Click here to unselect the file.” It sounded a little strange. Most software I had used always said “deselect.”
That small detail started an interesting discussion with editors, developers, and technical writers. Was unselect actually wrong? Or was it simply less common?
If you have searched for “unselect or deselect,” you probably had the same question. Maybe you’re writing documentation, creating a website, building an app, or simply trying to choose the right word.
The good news is that the answer is simple once you understand how both words are used.
By the end of this guide, you’ll know which word sounds more natural, when each one is acceptable, and how to avoid a mistake that makes writing look less professional.
Unselect or Deselect: Quick Answer
Deselect is the preferred word in English. It means to remove a selected item from a list, document, or computer interface.
Unselect has the same basic meaning, but it is far less common. Some software products use it, but most style guides and technical writers recommend deselect.
Examples
- Click the checkbox to deselect the item.
- Press Ctrl and click to deselect multiple files.
Less common:
- Click here to unselect the item.
The Origin and Background of Unselect and Deselect
The word select comes from the Latin word selectus, meaning “chosen.”
English often creates opposite meanings by adding prefixes.
- De usually means remove, reverse, or undo.
- Un usually means not or reverse, depending on the word.
Because de commonly describes removing an action, deselect became the natural choice in computing.
As graphical user interfaces became popular during the 1980s and 1990s, software companies used deselect in menus, manuals, and help documents. Over time, it became the industry standard.
Some developers still use unselect, especially in internal tools or code, but it is much less common in user facing writing.
