Inclosed vs Enclosed: Meaning, Correct Spelling, and Modern Usage

Understanding the Difference Between Inclosed and Enclosed

Many people searching Inclosed vs Enclosed wonder which spelling is correct. The confusion exists because both words share a similar history, but Enclosed is the accepted form in modern English. Inclosed was used in older literature, English-language books, and published essays, but it has declined over the centuries. Ngram graphs from 1800 to 2000 show that Enclosed became the preferred verb, while Inclose, inclosing, inclosure, and other variants are now mostly found in poetic contexts.

Using the right word is important in business, legal, and academic writing. Whether you write emails, letters, academic papers, legal papers, official documents, or business correspondence, choosing Enclosed helps you follow correct spelling, proper usage, and accepted writing standards. When you insert or enclose a document, papers, important details, or a small thing inside an envelope, mailed package, or package, your professional writing becomes more credible, clear, and easy to understand.

As an editor, I always recommend reviewing the context, terminology, terms, usage, examples, derived words, and corresponding sources before sending any message. This simple habit improves clarity, precision, confidence, and communication, while helping writers avoid common mistakes, misspelling, misunderstanding, and second-guessing. Understanding the difference, origin, historical spelling, language evolution, frequency, and accepted variants gives you the confidence to write accurate, natural, and professional English every time.

Quick Answer: Is Inclosed or Enclosed Correct?

Enclosed is the standard spelling for modern writing.

Use it when something:

• Is surrounded by walls, fences, or other barriers
• Is contained inside something
• Is placed in an envelope or package
• Has been closed in
• Accompanies a physical letter

Correct examples include:

• The backyard is fully enclosed.
• Please return the enclosed application.
• I enclosed a copy of the receipt.
• The equipment must remain in an enclosed area.

Inclosed can carry the same basic meaning. However, it is a less common variant and may appear old-fashioned or incorrect to modern readers.

Therefore, use enclosed in schoolwork, business writing, professional emails, reports, applications, websites, and everyday communication.

The difference is not mainly about meaning. Instead, it concerns frequency, convention, and reader expectations.

What Does Enclosed Mean?

Enclosed is the past-tense form and past participle of the verb enclose. It can also function as an adjective.

The verb enclose has two common ideas:

1. To surround or close something in
2. To put something inside an envelope, parcel, or package

These meanings appear in both American and British dictionary sources.

Enclosed as the Past Tense of Enclose

Use enclosed when an action happened in the past.

• The builders enclosed the porch last summer.
• A stone wall enclosed the garden.
• I enclosed a check with my application.
• The package enclosed the product securely.

In these examples, enclosed describes a completed action.

The full verb pattern is:

Verb Form	Example
Base form	enclose
Third-person singular	encloses
Past tense	enclosed
Past participle	enclosed
Present participle	enclosing

For example:

• I usually enclose a receipt.
• She encloses a return label.
• They enclosed the patio.
• We have enclosed the requested documents.
• He is enclosing a signed copy.

Enclosed as a Past Participle

A past participle often appears with a helping verb such as has, have, had, is, was, or were.

• We have enclosed the signed agreement.
• The yard was enclosed by a wooden fence.
• The documents are enclosed in a sealed envelope.
• The patio had been enclosed before the house was sold.

The helping verb and participle work together to form a verb phrase.

For instance, was enclosed uses the passive voice. It focuses on the yard rather than the person who built the fence.

Enclosed as an Adjective

Enclosed can also describe a noun. In that role, it acts as an adjective.

• an enclosed porch
• an enclosed courtyard
• an enclosed trailer
• an enclosed workspace
• the enclosed application

An enclosed porch is surrounded by walls, screens, windows, or similar structures. Meanwhile, an enclosed application is an application placed inside the same envelope or package.

The surrounding sentence makes the meaning clear.

What Does Inclosed Mean?

Inclosed is a less common spelling of enclosed. It comes from the verb inclose, which dictionaries may list as a variant of enclose.

Merriam-Webster labels inclose as a less common variant. The American Heritage Dictionary also records enclose with inclose as an alternative form. Therefore, calling inclosed completely nonexistent would be inaccurate. Still, it is not the form most modern readers expect.

Is Inclosed a Misspelling?

The answer depends on context.

Historically and lexically, inclosed has been used as a variant. Therefore, it is not simply an invented collection of letters.

However, in ordinary modern writing, many readers will assume it is a spelling mistake. They are accustomed to seeing:

• enclosed yard
• enclosed document
• enclosed porch
• enclosed payment
• enclosed space

For that reason, enclosed is the safer and clearer choice.

Why Inclosed Looks Possible

The spelling inclosed may seem logical because the prefix in- often relates to being inside.

English has many words beginning with in-, including:

• include
• insert
• interior
• internal
• inside

However, word formation does not always follow a simple modern pattern. The established standard verb is enclose, so its regular forms are enclosed, encloses, and enclosing.

You should not choose a spelling only because its parts appear logical. Instead, follow current standard usage.

When Inclosed May Be Appropriate

You may retain inclosed in a few limited situations:

• An exact quotation from an old book
• A historical letter or diary
• An archived legal record
• A transcription that preserves original spelling
• A proper name or official historical title
• A discussion about the spelling itself

For example:

The 19th-century record states that the land was “inclosed by a timber fence.”

Here, changing inclosed could make the quotation inaccurate. Outside the quotation, however, a modern writer would normally use enclosed.

The Main Difference Between Inclosed and Enclosed

The central difference is modern acceptability, not a dependable difference in meaning.

Both forms have been used for the ideas of surrounding, confining, or placing something inside. Yet enclosed became the standard spelling readers recognize today.

Enclosed Is the Standard Modern Form

Choose enclosed for:

• Essays
• Exams
• College applications
• Résumés and cover letters
• Business letters
• Contracts
• Reports
• Government forms
• Product instructions
• News articles
• Website content
• Everyday messages

This form communicates the meaning without distracting the reader.

Inclosed Is a Rare Variant

Although dictionaries may record inclosed, using it creates unnecessary risk.

A teacher may mark it as an error. A client may think the document was not proofread. In addition, automated writing tools may flag it because the form is uncommon.

A rare word is not always wrong. However, effective writing depends on more than dictionary recognition. You must also consider what readers expect.

Are They Interchangeable?

They can represent the same basic idea, but they are not equally suitable in modern communication.

Consider these versions:

• Please review the enclosed invoice.
• Please review the inclosed invoice.

The second sentence can be understood. However, the first is natural, standard, and professional.

Therefore, treat the pair as unequal choices. Use enclosed unless you have a specific historical reason not to.

Enclosed as a Verb and an Adjective

The same spelling can perform different grammatical jobs.

Enclosed as a Verb

In the following sentence, enclosed shows an action:

• The contractor enclosed the balcony.

The subject, contractor, performed the action. The balcony received that action.

Another example is:

• I enclosed the payment with the form.

Here, the speaker placed the payment inside an envelope or package.

Enclosed as an Adjective

Now compare:

• We sat on the enclosed balcony.

In this sentence, enclosed describes the noun balcony. It tells you what kind of balcony it is.

Likewise:

• Please sign the enclosed form.

The word describes the form sent inside the letter.

How Sentence Position Changes the Role

Sentence	Role of Enclosed	Explanation
They enclosed the garden.	Verb	Describes an action
The garden was enclosed.	Past participle	Works with “was”
We entered the enclosed garden.	Adjective	Describes “garden”
I enclosed a photograph.	Verb	Means placed inside
The enclosed photograph is damaged.	Adjective	Describes “photograph”

Understanding the sentence role helps you identify the meaning.

How to Use Enclosed Correctly

Enclosed works in several common contexts.

When Something Is Surrounded

Use it when a boundary surrounds an area.

• The children played in an enclosed yard.
• A high wall enclosed the property.
• The hotel has an enclosed courtyard.
• Keep the dog in the enclosed area.

The boundary may be a fence, wall, screen, railing, or natural feature.

When Something Is Covered or Closed In

An area can be enclosed above as well as around its sides.

• The restaurant added an enclosed patio for winter.
• The truck has an enclosed cargo area.
• We waited inside an enclosed shelter.
• The balcony was fully enclosed with glass.

An enclosed place is not always airtight. The word mainly suggests that it is surrounded or separated from the open area around it.

When Something Is Inside a Letter or Package

Use enclosed for an item physically placed with other mailed materials.

• Please complete the enclosed form.
• I have enclosed a copy of my identification.
• The enclosed check covers the remaining balance.
• Sign and return the enclosed agreement.

Oxford’s American dictionary entry includes the meaning of putting something in the same envelope or package. It also lists enclosed for something sent with a letter.

When Something Is Contained

The word can also describe materials held within a structure or container.

• The gas remained enclosed in the chamber.
• Store the chemical in an enclosed container.
• The wires are enclosed in protective tubing.
• The machine operates as an enclosed system.

In technical writing, be precise about the type of containment. An enclosed system may still allow controlled movement, ventilation, or access.

Enclosed, Attached, and Included

These words overlap, but they are not exact synonyms.

Word	Best Used For	Example
enclosed	An item inside a physical letter or package	Please sign the enclosed form.
attached	A file connected to an email or message	I’ve attached the report.
included	Something that forms part of a group, price, service, or contents	Breakfast is included.
inserted	Something placed into a space or document	A card was inserted into the package.

Use Enclosed for Physical Mail

Traditional business letters often refer to physical materials as enclosed.

• Enclosed is your replacement card.
• Please review the enclosed contract.
• I have enclosed two copies of the agreement.

The item is literally inside the envelope or parcel.

Use Attached for Email Files

For digital communication, attached is usually clearer.

Natural:

• I’ve attached the invoice.
• The requested file is attached.
• Please review the attached document.

Less natural in a routine email:

• Please review the enclosed document.

The last sentence is understandable. However, readers may wonder whether the writer means a digital attachment or a physical enclosure.

Use Included for General Content

Included means something forms part of a larger group, amount, service, or package.

• Shipping is included in the price.
• The kit includes three replacement filters.
• Instructions are included with every order.
• Your name was included on the list.

You cannot always replace included with enclosed.

Incorrect:

• Breakfast is enclosed in the room rate.

Correct:

• Breakfast is included in the room rate.

Is “Please Find Enclosed” Correct?

Yes, please find enclosed is grammatically correct. It is especially suitable for a formal letter containing a physical document.

For example:

• Please find enclosed the signed contract.
• Please find enclosed a copy of your receipt.
• Please find the completed application enclosed.

However, the phrase can sound formal or dated in everyday business communication.

Clearer Alternatives for Letters

You can often write:

• I’ve enclosed the signed contract.
• The signed contract is enclosed.
• Enclosed is a copy of the receipt.
• Please review the enclosed application.

These options are direct and easy to read.

Better Alternatives for Email

For an email attachment, use:

• I’ve attached the signed contract.
• The signed contract is attached.
• Please review the attached file.
• You’ll find the report attached.

These sentences identify the delivery method clearly.

Is “Enclosed Please Find” Correct?

Enclosed please find appears in older business correspondence. Readers can understand it, but its inverted word order sounds stiff today.

Instead of:

• Enclosed please find our completed application.

Write:

• Our completed application is enclosed.
• We have enclosed our completed application.

For email, write:

• We have attached our completed application.

Correct Examples of Enclosed

The following examples show how the word works across different settings.

Physical Spaces

• The apartment has an enclosed balcony.
• A metal fence enclosed the playground.
• Employees must smoke only in the enclosed area.
• The resort offers an enclosed pool for winter use.

Letters and Packages

• I enclosed the original receipt.
• Please return the enclosed questionnaire.
• The enclosed label provides the return address.
• A warranty card is enclosed with the product.

Academic and Technical Writing

• Researchers stored the samples in an enclosed container.
• The experiment took place in an enclosed chamber.
• The diagram represents an enclosed system.
• Each specimen was enclosed in a separate case.

Workplace Communication

• The enclosed proposal includes the updated budget.
• We enclosed two signed copies for your records.
• Please review the enclosed payment schedule.

Everyday American English

• The cat escaped from the enclosed patio.
• I enclosed some photos with the birthday card.
• The trailer provides enclosed storage.

Inclosed and Enclosed in American and British English

Inclosed vs enclosed is not a normal American-versus-British spelling pair.

Real regional spelling differences include:

American English	British English
color	colour
center	centre
canceled	cancelled
traveled	travelled

By contrast, enclosed is standard in both present-day American and British English. Oxford provides enclose and enclosed in both its general learner and American dictionary entries.

Therefore, switching to British English does not create a reason to write inclosed.

You may still find the variant in historical British or American material. That reflects age, individual spelling, publishing practice, or preserved source language rather than a simple regional rule.

Common Mistakes With Inclosed and Enclosed

Several nearby words cause confusion.

Using Inclosed in Modern Professional Writing

Avoid:

• The inclosed invoice is due Friday.

Prefer:

• The enclosed invoice is due Friday.

The first spelling may have dictionary history. However, the second matches modern professional expectations.

Using Enclose Instead of Enclosed

Incorrect:

• Please review the enclose document.

Correct:

• Please review the enclosed document.

The base verb enclose cannot directly describe document in this structure. You need the adjective or past participle enclosed.

Compare:

• Please enclose the document.
• Please review the enclosed document.

The first sentence gives an instruction. The second identifies the document.

Using Enclosed When Attached Is Clearer

Awkward in a routine email:

• I have enclosed the spreadsheet.

Clearer:

• I have attached the spreadsheet.

However, enclosed is still correct when the email discusses a physical space:

• The photograph shows an enclosed staircase.

The communication method does not change the word’s physical meaning.

Confusing Enclosed With Included

Incorrect:

• Internet service is enclosed in the monthly price.

Correct:

• Internet service is included in the monthly price.

Included means it forms part of the total. Enclosed suggests physical or conceptual containment.

Confusing Enclosed With Closed

A closed place is shut, unavailable, or not operating. An enclosed place is surrounded.

Compare:

• The store is closed on Sunday.
• The mall has an enclosed play area.

A business can be open while its patio is enclosed. Likewise, an outdoor business can be closed without being enclosed.

Confusing Enclosed With Sealed

Sealed suggests that an opening has been secured to prevent access, leakage, or contamination.

• The medication arrived in a sealed package.
• The animals remained in an enclosed field.

A field may be enclosed by a fence but not sealed. A bottle may be sealed even though you would not normally call the surrounding room enclosed.

Confusing Enclosed With Encased

Encased often suggests a close or protective covering.

• The phone was encased in rubber.
• The courtyard was enclosed by brick walls.

Rubber closely covers the phone. The walls surround the courtyard at a greater distance.

• encircled

Pronunciation and Spelling of Enclosed

Enclosed is pronounced approximately in-KLOHZD in American English. The final part contains the sound of close as a verb, followed by a d sound. Cambridge gives the American pronunciation as /ɪnˈkloʊzd/.

Compare:

• close the door: klohz
• enclosed area: in-klohzd

The final consonant group may sound compressed in fast speech. However, the spelling remains enclosed.

How to Spell Enclosed

Start with the base verb:

• enclose

Then add d:

• enclose + d = enclosed

Because enclose already ends in e, you add only d, not another full -ed spelling.

The same pattern appears in:

• use + d = used
• close + d = closed
• change + d = changed
• provide + d = provided

A Simple Memory Trick

Connect enclosed with envelope:

Something enclosed may be inside an envelope.

• You are listing contents or features
• Physical containment is not the main idea

Practical Communication Scenarios

• Please review the enclosed résumé and reference list.

Here, enclosed accurately describes physical documents inside the mailing envelope.

A Job Application Sent by Email

The same candidate sends PDF files electronically.

Best wording:

• I’ve attached my résumé and reference list.

Using attached prevents confusion about how the files were delivered.

A Construction Report

An inspector describes a porch surrounded with walls and windows.

Best wording:

• The home includes a fully enclosed porch.

In this case, enclosed describes the physical design.

A Historical Research Paper

A student quotes a deed that uses the spelling inclosed.

Best approach:

The deed describes the parcel as “inclosed by a stone wall.”

The student should preserve the original spelling inside the quotation. Outside it, the paper should use enclosed.
