What Does “Deselect” Mean? (Preferred Word)
Deselect means to remove a selection or unmark something that was previously selected.
It appears in dictionaries, in UI guidelines, and throughout professional writing.
Simple definition:
To clear a chosen option, item, or checkbox.
Examples
- Deselect the file before deleting the folder.
- Click “Deselect All” to start fresh.
Where it’s used most
- Software menus
- Checkboxes and radio buttons
- Interface instructions
- Technical documentation
- Academic and professional writing
Quick grammar note
The prefix de- means reverse or remove, which fits perfectly:
| Prefix | Meaning | Example |
| de- | remove, reverse, undo | deactivate, defrost, deregister, deselect |
So deselect matches standard English prefix rules.
✅ Correct in dictionaries
✅ Professional and accepted
✅ Clear in software and written English
✅ Best default choice
What Does “Unselect” Mean? (Informal Alternative)
Unselect has one job: to mean the same thing as “deselect” — but it’s not traditionally recognized in formal English.
Simple definition:
To remove a selection, especially in informal tech contexts.
Examples
- Tap again to unselect the images.
- You can unselect items with a long press.
Recognition
Many dictionaries still don’t include it; some mention it as colloquial tech usage.
In other words, it’s understandable, but not universally accepted.
Why it exists
Tech language evolves fast. Programmers and UI designers need short, intuitive words. The un- prefix feels natural because we use:
- unlock
- undo
- unmute
- uncheck
So “unselect” sounds right — even if grammar purists frown a little.
⚠️ Widely used in casual speech
⚠️ Appears in software and online tools
❌ Not preferred for formal writing
Quick Comparison Table: Unselect vs Deselect
| Word | Correct? | Formality | Usage | Example |
| Deselect | ✅ Yes | Professional & standard | Software manuals, UI buttons, writing | Deselect all items before saving. |
| Unselect | ⚠️ Informal | Casual / tech slang | Mobile apps, speech, quick UI text | Unselect photos with one tap. |
Bottom line:
If you’re unsure, use “deselect”.
Why “Deselect” Wins in Grammar
A quick linguistic dive:
Prefix Rules
| Prefix | Role | Word Example | Logic |
| de- | remove, reverse | deselect, deinstall, deactivate | Undoing or reversing |
| un- | opposite | undo, unlock, unfit | Opposite of a state, not action |
We undo actions, but we deselect items.
The nuance matters in language structure.
Dictionary and Style Guide Support
- Oxford, Merriam-Webster, Cambridge list deselect
- “Unselect” appears occasionally, often marked informal or tech-specific
Grammar rule:
Use “deselect” because it follows English morphology standards.
Where Tech Breaks the Rule (and Why It Works)

If a term feels intuitive on a screen, designers may pick it.

| Some Android apps | “Unselect” |
