When choosing between unselect vs deselect, the issue is not simply that one spelling is correct and the other is wrong. Both forms are attested in English, particularly in computing and interface contexts, but they do not have the same level of standardization or the same stylistic status. Deselect is the established dictionary-listed verb used for removing something from a selection, while unselect is also used, especially in technical contexts, with essentially the same practical meaning. Oxford lists deselect specifically for computing, and other dictionaries and usage sources attest unselect as a verb.
This guide explains their meanings, pronunciation, grammatical behavior, usage differences, spelling patterns, and when each form is appropriate.

What Does “Unselect vs Deselect” Mean?
The phrase unselect vs deselect refers to a word-choice question involving two verbs that can describe reversing a selection.
What Does “Deselect” Mean?
Deselect means to remove something from a selection or to cancel its selected status.
In computing, for example, you might:
- deselect a file
- deselect an option
- deselect an item
- deselect highlighted text
- deselect a menu choice
Oxford specifically records deselect as a computing verb meaning to remove something from the list of possible choices on a computer menu.
What Does “Unselect” Mean?
Unselect is also used as a verb for reversing a previous selection, particularly in computing contexts.
For example:
- Unselect the files you do not want to upload.
- The user accidentally unselected the item.
WordWeb defines unselect in computing as changing an item in a user interface from a selected state to an unselected state. Reverso likewise records it as a technology term for cancelling a previous selection.
The Basic Difference
In many software-related sentences, unselect and deselect refer to essentially the same action.
The more important difference is usage and lexical status, not a fundamental difference in the action being described.
Deselect has stronger support from major established dictionaries and is therefore the more conservative choice for formal technical writing. Unselect is nevertheless an attested English verb and should not simply be dismissed as a nonexistent word.
Is “Unselect” Correct?
Yes, unselect is an attested English verb, particularly in computing and interface-related usage. It should not automatically be described as a spelling mistake.
WordWeb gives unselect as a computing verb, while Reverso also records it with the meaning of cancelling a previous selection.
However, deselect is the more firmly established choice in major dictionary sources for the relevant computing sense. Oxford lists it explicitly as a computing verb.
Therefore:
For formal, professional, or technical writing, “deselect” is generally the safer choice.
That does not mean every occurrence of unselect is an error.
Avoid common spelling confusion by learning Vicious vs Viscous usage examples that show how each adjective works in context.
Is “Deselect” Correct?
Yes. Deselect is a standard English verb.
Oxford records both its political and computing uses, including the computing sense of removing something from a list of possible choices on a computer menu.
Collins also records deselect as a verb with several meanings, including cancelling a highlighted selection on a computer screen and removing a check mark from an option in a dialogue box.
So if you need a conventional term for software instructions, deselect is a well-established choice.
What Is the Correct Spelling?
Both unselect and deselect are correctly formed English spellings.
The important point is that they represent different prefix formations:
- un- + select → unselect
- de- + select → deselect
The two forms have developed different levels of conventional acceptance and usage.
If your question is specifically about the word normally preferred in technical documentation, software instructions, or formal explanatory writing, use:
Correct standard choice: deselect
If you encounter unselect, do not automatically treat it as a typographical error. It is an attested form used in computing contexts.
Difference Between the Forms
| Feature | Unselect | Deselect |
| Status | Attested English verb | Established dictionary-listed verb |
| Meaning | Reverse or cancel a selection | Remove something from a selection |
| Word Type | Verb | Verb |
| Pronunciation | /ˌʌnsɪˈlekt/ | /ˌdiːsɪˈlekt/ |
| Usage | Particularly found in computing and interface language | Computing, technical usage, and other established senses |
| Modern Standard Usage | Used, but less firmly standardized | Strongly established |
| Formal Writing | Possible, but may be less conventional | Usually the safer choice |
| Software Instructions | Understandable | Conventional choice |
The practical distinction is therefore mainly one of conventionality and register.
For example:
Please deselect the files you do not want to send.
This is conventional technical wording.
You may also encounter:
Please unselect the files you do not want to send.
The meaning is readily understandable, and unselect is attested in computing usage.
Meaning of “Deselect”
Computing Meaning
In computing, deselect refers to removing an item from an existing selection or removing its selected status.
Examples include:
- removing a file from a group of selected files
- removing a highlighted item from a selection
- cancelling an option that has been selected
- removing a check mark from an option
Oxford specifically identifies this computing sense.
Other Meaning
Deselect also has a specialized British political meaning. In that context, it can refer to a local political party choosing not to retain an existing Member of Parliament as its candidate for a subsequent election. Cambridge and Oxford both record this sense.
That meaning is separate from the computing use.
Common Contexts
You may encounter deselect in:
- software instructions
- menus
- forms
- file-management tools
- search interfaces
- image-editing applications
- selection tools
- technical documentation
Pronunciation
IPA Pronunciation
For deselect, Cambridge gives the pronunciation:
UK: /ˌdiː.səˈlekt/
US: /ˌdiː.səˈlekt/
Oxford represents it as:
/ˌdiːsɪˈlekt/
These representations use slightly different conventions for showing the unstressed vowel, but they describe the same general pronunciation.
For unselect, Reverso gives:
/ˌʌnsɪˈlɛkt/
Syllable Breakdown
A practical syllable division is:
- de-select
- un-select
The primary stress falls on the final syllable:
- de-se-LECT
- un-se-LECT
Pronunciation Tips
The important contrast is at the beginning:
- deselect begins with a /diː/ sound
- unselect begins with an /ʌn/ sound
The second part, select, is pronounced the same way in both words.
Do not change the pronunciation of select simply because the prefix changes.
Why Do People Confuse “Unselect” and “Deselect”?
The confusion is understandable because both forms combine a prefix with the familiar verb select.
Several factors contribute to the uncertainty.
Both Forms Express Reversal
The practical action is often the same: an item that was selected is no longer selected.
That makes sentences such as these semantically very close:
Deselect the image.
Unselect the image.
The Prefixes Suggest Similar Ideas
English uses un- in many verbs to indicate reversal or removal of a previous action:
- unlock
- undo
- unpack
- uncheck
The form unselect therefore looks completely understandable.
English also has many verbs formed with de-, including:
- deactivate
- declassify
- deconstruct
- decode
So deselect also looks structurally natural.
Software Language Creates New Terminology
Computing has produced and popularized many specialized verbs. In user-interface language, a term can become established through repeated technical use even when speakers may initially find another construction equally understandable.
This is one reason unselect appears in actual computing usage even though deselect has stronger dictionary support for this particular sense.
Origin and Etymology
The two words have different prefix formations.
Deselect
Deselect is formed from de- + select. Collins gives its word origin as de- + select and dates the formation to the 1960s.
The verb therefore developed as a reversal or removal counterpart to select.
Unselect
Unselect is transparently formed from un- + select. Reverso identifies its origin as English un- plus select, while WordWeb records the resulting verb in computing usage.
The important point is that the existence of the two formations does not mean that one must be a spelling mistake. English can create competing formations with related meanings.
How to Remember the Correct Spelling
If you are writing software instructions, remember:
Select → Deselect
The pair is especially useful because deselect is the established dictionary term used for the computing action.
Quick Memory Trick
Think:
Select it, then deselect it.
The two words form a natural instructional pair.
Word-Family Connection
The most useful related forms include:
- select
- selected
- selecting
- selector
- selection
- deselect
- deselected
- deselecting
- deselection
Oxford lists the standard inflected forms deselects, deselected, and deselecting.
For interface terminology, also remember:
Select → Deselect
and, when dealing specifically with a checkbox:
Check → Uncheck
Collins defines uncheck in computing as removing a check mark and gives deselect as a synonym.
Examples in Sentences
Because both verbs are attested, the examples below show how each can be used while also illustrating why deselect is generally the more conventional choice for formal technical instructions.
| Deselect Example | Unselect Example |
| Please deselect any files you do not want to upload. | Please unselect any files you do not want to upload. |
| Deselect the image before choosing a different editing tool. | Unselect the image before choosing a different editing tool. |
| The user deselected the wrong document by accident. | The user unselected the wrong document by accident. |
| Deselect the option if you do not want automatic updates. | Unselect the option if you do not want automatic updates. |

| Deselect the remaining items before changing the filter. | Unselect the remaining items before changing the filter. |
| The interface allows you to deselect previously chosen files. | The interface allows you to unselect previously chosen files. |
These examples illustrate the semantic overlap between the two forms. The choice is therefore usually about conventional terminology rather than a completely different action.
Common Mistakes to Avoid
- Do not automatically call unselect a misspelling. It is attested as a verb in computing usage.
- Do not assume deselect is restricted to computers. It also has specialized non-computing uses.
- Do not confuse deselect with uncheck. Uncheck specifically concerns removing a check mark from a checkbox.
- Do not write deselect from automatically. In many sentences, the direct-object construction is clearer: deselect the file.
- Do not treat the prefixes as interchangeable spelling rules. un- and de- have different histories and patterns of use.
- Do not assume every software product must use the same terminology. Product-specific terminology can differ from general English usage.

Synonyms and Near-Synonyms
The appropriate alternative depends on what is being removed.
Deselect can overlap with:
- uncheck
- remove from the selection
- clear the selection
- cancel the selection
These are not always interchangeable.
For example, uncheck is especially appropriate when the interface contains a checkbox. Collins explicitly defines uncheck in computing as removing a check mark and equates it with deselect.
Antonyms

Grammar Tips
Both Forms Function as Verbs
When used as verbs, both forms can take a direct object:
Deselect the option.
Unselect the option.
The verb normally appears directly before the thing whose selected status is being changed.
Past Tense
Both forms take the regular -ed ending:
- deselect → deselected
- unselect → unselected
Present Participle
Again, both use regular verb formation:
- deselect → deselecting
- unselect → unselecting
Noun Formation
The established noun associated with deselect is deselection. Oxford and Cambridge both record deselection.
For professional writing, it is better not to invent a noun such as unselection merely because unselect exists. Choose the established noun appropriate to the context.
Writing Tips
If you are writing software documentation, help articles, instructions, or professional copy, consistency matters.
A practical approach is:
- Use deselect when you need the established technical term.
- Use uncheck when the action specifically removes a checkbox mark.
- Use remove from the selection when absolute clarity matters more than brevity.
- Follow a product’s established terminology when documenting an existing interface.
- Avoid switching randomly between unselect and deselect within the same document.
For example, if your instructions say:
Select the files you want to keep.
then the corresponding reversal can naturally be:
Deselect the files you want to remove.
This creates a clear and consistent terminology pair.

Conclusion
The choice between unselect vs deselect is primarily a question of established usage, not simply right spelling versus wrong spelling. Deselect is the more firmly established term, particularly in computing terminology, and it is the safer choice for formal documentation, instructions, and professional writing. Oxford explicitly records its computing use, while other sources attest unselect as a verb used for reversing a selection.
The easiest memory aid is select → deselect. When you are writing instructions for software, forms, menus, or other interfaces, this pairing provides familiar and precise terminology. At the same time, seeing unselect in actual English usage does not automatically mean that the writer has made a spelling mistake. Context and established terminology both matter.
Frequently Asked Questions
Is “unselect” a correct English word?
Yes. Unselect is an attested English verb, particularly in computing and user-interface contexts. WordWeb records it as a computing verb, and Reverso also lists it with the meaning of reversing or cancelling a previous selection. It is therefore inaccurate to describe every occurrence of unselect as simply a spelling error.
Is “deselect” the correct word?
Yes. Deselect is an established English verb. Oxford specifically records its computing meaning as removing something from the list of possible choices on a computer menu. Collins also records computing uses involving cancelling a highlighted selection or removing a check mark from an option.
Which is better, unselect or deselect?
For formal and professional technical writing, deselect is generally the safer choice because it has stronger support as an established dictionary term for the relevant computing sense. Unselect is nevertheless an attested form. The distinction is therefore better described as one of conventionality and usage rather than simply correct versus incorrect spelling.
What does deselect mean in computing?
In computing, deselect means to remove something from an existing selection or cancel its selected status. For example, if several files are highlighted and you click one to remove it from the group, you can say that you deselected that file. Oxford specifically records this computing use.
What does unselect mean?
Unselect means to reverse or cancel a previous selection. It is particularly attested in computing terminology. For example, unselect the file means to remove the file from its selected state. WordWeb and Reverso both record this use.
Is “unselect” a misspelling of “deselect”?
No. Unselect should not automatically be treated as a misspelling of deselect. It is an attested verb with a recognizable computing meaning. However, deselect is the more established dictionary-listed term for the computing sense, so it is usually the more conventional choice when you are writing formal documentation.
How do you pronounce “deselect”?
