They both mean removing a selection, but only one meets professional standards.

Unselect vs. Deselect – Key Difference

Both terms point to the same action—reversing a selection. But the way they’re used and accepted makes all the difference in professional contexts.

Deselect means to cancel or remove an item that was previously selected. It’s the formal, dictionary-approved term used across technical writing, software documentation, and user experience design.

Deselect is a verb that means to remove the selected status from an item, checkbox, or element. When you click a selected checkbox again, you deselect it.

The term gained widespread use in the 1990s as digital interfaces became common. Software needed clear language for reversing selections, and deselect emerged as the standard.

Is “Unselect” a Real Word or Just Tech Slang?

Unselect is not listed in major dictionaries. Merriam-Webster, Oxford, and Cambridge don’t recognize it as a standard English word.

Despite lacking dictionary approval, unselect appears regularly in software interfaces and developer discussions. It’s understood by users but considered nonstandard in professional writing.

The Microsoft Style Guide specifically instructs writers to use deselect when referring to clearing checkboxes or reversing selected states.

Deselect vs Unselect

When You Can Use “Unselect” (And When You Shouldn’t)

Unselect isn’t always wrong—but its use should be limited to specific, informal contexts.

The term works acceptably in casual conversation, internal team communications, or extremely space-constrained UI buttons where character count matters.

Acceptable Contexts for Using Unselect

You can use unselect in these limited situations:

• Casual verbal instructions during presentations or demos
• Internal documentation not shared with customers
• UI buttons where space is severely limited (though “Clear” works better)
• Informal blog posts or social media content

Even in these contexts, deselect remains the safer, more professional choice.

Real-World Examples

Seeing both terms used correctly helps clarify when each might appear.

Software Documentation Examples

Correct professional use:

• “To deselect all items, press Ctrl+Shift+A.”
• “Deselect the checkbox before submitting your form.”
• “Click the highlighted cell again to deselect it.”

User Interface Button Labels

Common UI patterns:

• “Deselect All” (preferred in professional software)
• “Clear Selection” (excellent alternative)
• “Unselect” (appears in some mobile apps, but not recommended)

Survey data from UX research shows that “Deselect All” performs 23% better in usability testing than “Unselect All” because users recognize it faster.

Better Alternatives to Both Terms

Sometimes neither unselect or deselect fits your needs. Plain language alternatives work beautifully:

• “Clear the checkbox”
• “Remove your selection”
• “Undo your choice”
• “Uncheck this box”
• “Turn off this option”

These phrases are accessible, clear for all reading levels, and avoid technical jargon entirely.
