Unselect and deselect are two words that are often used when talking about options, checkboxes, buttons, menus and selected items. Because both appear to mean the opposite of select, many people wonder whether one is correct and the other is wrong. The answer depends partly on context but one form is generally more established and natural in standard English.
Deselect is the preferred and widely recognized term for removing a selection. It is especially common in software, websites, forms, applications and technical instructions. Unselect is also used, particularly in informal and user interface contexts but it is generally less preferred than deselect in polished writing. If you are writing instructions, documentation or professional content, deselect is usually the safest choice.
Quick Answer
Deselect is the preferred term when you mean to remove an existing selection. Unselect is also used and is understandable, especially in informal or software related contexts, but deselect is more established and generally sounds more natural in formal instructions and technical documentation.
Why Do People Confuse Unselect and Deselect?
The confusion comes from the prefixes un- and de-.
English uses un- to create words that often describe reversing an action:
- lock → unlock
- tie → untie
- pack → unpack
- connect → disconnect
English also uses de- for words involving removal or reversal:
- activate → deactivate
- centralize → decentralize
- code → decode
- select → deselect
Because unselect seems logically possible as the opposite of select people naturally use it. However, deselect has become the more established term for removing a selection.
This is particularly true in computing and interface language.
Deselect
Deselect means to remove a selection that was previously made.
If you select an option and then remove that selection, you deselect it.
Meaning of Deselect
In simple English:
Deselect = remove a selection.
For example:

The word can be used as a verb.

Unselect
Unselect is understandable and is used by some speakers and software interfaces to mean deselect.

The meaning is clear, but deselect is generally the more established and preferred choice.
Is Unselect Wrong?
Not necessarily.
Unselect occurs in real-world English, especially in computing and informal instructions. However, if you are choosing between the two for polished writing, deselect is usually the better option.
Instead of:
Unselect the box.
Prefer:
Deselect the box.
The second version is more conventional and professional.

Common Mistakes
Mistake 1: Assuming Unselect Is Always Wrong
It is better to say that unselect is less preferred, rather than claiming that it can never be used.
The word appears in actual usage and is easily understood.
Mistake 2: Using “Unselect” in Formal Documentation
Less preferred:
Unselect the checkbox to continue.
Better:
Deselect the checkbox to continue.
Mistake 3: Confusing Deselect With Delete
These words do not mean the same thing.
Deselect means to remove a selection.
Delete means to remove something itself.
For example:
Deselect the file.
means you are no longer selecting the file.
Delete the file.
means you are removing the file.
Mistake 4: Thinking Deselect Means “Never Select”
It does not.
Deselect means to remove a selection that already exists.
Memory Trick
Think of:
Select → Deselect
Just as:
Activate → Deactivate
Connect → Disconnect
Select → Deselect
So when you want to say “remove the selection,” remember:
Deselect = remove a selection.
You can also remember:
Select it → Deselect it.
