Enclose vs. Inclose: Why Enclose Is the Modern Standard

The enclose vs. inclose choice is simple: enclose is the modern spelling, while inclose survives mainly in older historical records and texts. Both words once meant to surround, shut in, or place something inside a container, boundary, or envelope.

Today, enclose is the accepted verb in modern English. Its related forms are enclosed, enclosing, and enclosure. You can enclose a yard with a fence, enclose a document in a letter, or describe an enclosed space. This spelling fits school, business, and formal writing.

Use inclose only when quoting an old source or naming something historical, such as the Inclosure Acts. Older forms like inclosed, inclosing, and inclosure may appear in legal records or classic literature. In new writing, they can look like misspellings. A simple rule helps: use enclose for current writing and keep inclose only when historical accuracy requires it.

Quick Answer: Is It Inclosed or Enclosed?

Use enclosed in modern English.

The word enclosed can mean:

• Surrounded by a physical boundary
• Placed inside a letter, envelope, or package
• Included as part of a physical delivery
• Closed off from an open area

Examples:

• The yard is enclosed by a wooden fence.
• The payment is enclosed with this letter.
• The animals stayed in an enclosed area.
• A copy of the receipt is enclosed.

Inclosed is a historical spelling of the same word. It may be preserved in old legal records, books, maps, or direct quotations. However, it is not the recommended form for normal school, business, academic, or professional writing.

Simple rule: Use enclosed unless you are quoting an older source that originally uses inclosed.

Inclosed vs. Enclosed at a Glance

Word	Modern status	Meaning	Recommended use	Example
enclosed	Standard	Surrounded, contained, or included inside something	Use in modern writing	The form is enclosed.
inclosed	Archaic or historical	Older variant of enclosed	Use only in quotations or historical discussion	The original deed says “inclosed land.”
enclose	Standard base verb	To surround or place inside	Use for present or future actions	Please enclose the receipt.
enclosure	Standard noun	An enclosed area or an item included with a letter	Use in modern writing	The animals entered the enclosure.

The two spellings do not represent two different modern meanings. Instead, enclosed became the accepted standard form.

What Does Enclosed Mean?

Enclosed is the simple past and past participle form of the verb enclose. It can also work as an adjective.

The verb enclose means to surround, contain, or place something inside another object.

For example:

• The fence enclosed the garden.
• She enclosed a check with the application.

The form enclosed may describe a completed action:

• They enclosed the porch last year.

It may also describe the condition of something:

• The porch is fully enclosed.

Therefore, the exact meaning depends on the sentence.

Enclosed Meaning “Surrounded or Contained”

One common meaning of enclosed is surrounded by a physical boundary.

The boundary may be made of:

• Walls
• Fences
• Glass
• Metal
• Fabric
• Hedges
• Barriers
• A container

Examples:

• The playground is enclosed by a high fence.
• We sat in an enclosed courtyard.
• The equipment must remain in an enclosed cabinet.
• The balcony is fully enclosed with glass.
• The dog stayed in an enclosed yard.

In these examples, the enclosed place has clear limits around it.

However, enclosed does not always mean airtight or completely sealed. A fenced yard may be enclosed even if it has an open gate. An enclosed porch may have windows that can open.

The word focuses on the surrounding boundary, not necessarily on complete closure.

Enclosed Meaning “Included Inside Something”

The second major meaning appears in letters, packages, applications, and business communication.

When an item is enclosed, it has been placed inside another physical item.

Examples:

• I have enclosed the signed agreement.
• The receipt is enclosed with your order.
• Please review the enclosed documents.
• A return label is enclosed in the package.
• The application includes an enclosed payment form.

This usage was especially common when businesses sent most documents by mail.

Today, it still applies to physical letters and packages. However, attached is usually the better word for digital files sent by email.

Is Inclosed a Real Word?

Yes, inclosed has existed in English. However, that does not make it the best spelling for modern writing.

Historically, inclosed appeared as a variant of enclosed. Older writers did not always follow the same spelling standards used today. As a result, several words appeared in more than one form.

You may find inclosed in:

• Historical property documents
• Old court records
• Early dictionaries
• Older books and letters
• Land surveys
• Legal quotations
• Preserved place names
• Transcriptions of original sources

For example, an old deed might describe “inclosed land.” When quoting the deed exactly, you should preserve its original spelling.

However, when explaining the same information in modern English, write:

• The deed describes enclosed land.

This keeps the quotation accurate while making your explanation clear.

Why Did Inclosed and Enclosed Both Exist?

The spellings developed during a period when English spelling was less fixed than it is today.

The prefixes in- and en- can both carry the idea of putting something into a state or place. English borrowed and developed words from several languages, including French and Latin. As spelling conventions changed, some forms became more common than others.

Over time, enclose became the standard verb. Therefore, its related forms also became standard:

• enclose
• encloses
• enclosed
• enclosing
• enclosure

The older form inclose remained visible in some records, but it gradually became rare.

For modern writers, the language history is less important than the practical result: enclosed is the expected spelling today.

The Main Difference Between Inclosed and Enclosed

The clearest difference is their status in modern English.

Enclosed Is the Modern Standard

Use enclosed in:

• School assignments
• Business letters
• Reports
• Articles
• Contracts written today
• Product instructions
• Property descriptions
• Emails discussing physical documents
• Everyday conversation

Example:

• The pool is enclosed by a safety fence.

This spelling looks natural and professional to modern readers.

Inclosed Is a Historical Variant

Use inclosed only when:

• Quoting an old source exactly
• Discussing historical spelling
• Preserving an official old title
• Referring to a proper name that uses that spelling

Example:

• The 1798 record uses the phrase “inclosed meadow.”

In this sentence, the older spelling is appropriate because it is part of a quotation.

Reader Expectations Matter

Even when readers can understand inclosed, many will assume it is a typo. That reaction can weaken confidence in the writing.

Compare:

• The documents are inclosed.
• The documents are enclosed.

The second version is clearer because it matches current spelling standards.

Enclosed as a Verb Form

The word enclosed can function as a verb in the past tense or as a past participle.

Enclosed in the Simple Past

Use the simple past when describing a completed action.

Examples:

• The builder enclosed the porch last summer.
• She enclosed a copy of her identification.
• The company enclosed the equipment in a protective case.
• We enclosed the garden with a metal fence.

In each example, the action happened and ended in the past.

Enclosed as a Past Participle

Use enclosed after helping verbs such as has, have, had, is, was, were, or been.

Examples:

• The contractor has enclosed the patio.
• I have enclosed the requested documents.
• The area was enclosed for safety.
• The receipt is enclosed with the letter.
• The animals had been enclosed before the storm arrived.

The helping verb shows tense or voice, while enclosed carries the main meaning.

Enclosed as an Adjective

Enclosed can also describe a noun.

Common adjective phrases include:

• an enclosed space
• an enclosed porch
• an enclosed garden
• an enclosed trailer
• the enclosed document
• the enclosed receipt
• an enclosed courtyard
• an enclosed staircase

The meaning depends on the noun.

For example:

• an enclosed patio means a patio surrounded by walls, screens, or glass.
• the enclosed invoice means an invoice placed inside a letter or package.

Context usually makes the meaning clear.

Enclosed in Letters and Business Writing

The word enclosed has a long history in formal correspondence.

A traditional business letter might say:

• Please find enclosed the signed agreement.
• Enclosed is a copy of the invoice.
• I have enclosed the requested payment.

All three examples are grammatically correct. However, they differ in tone.

Is “Please Find Enclosed” Correct?

Yes, please find enclosed is grammatically acceptable. However, it can sound formal, stiff, or old-fashioned.

For example:

• Please find enclosed the completed application.

A more direct version is:

• I have enclosed the completed application.

Another clear option is:

• The completed application is enclosed.

The best choice depends on your audience. A traditional legal or financial letter may still use please find enclosed. A modern business letter often benefits from simpler wording.

Enclosed vs. Attached in Email

Writers often use enclosed and attached as though they mean the same thing. However, the two words describe different situations.

Use enclosed when an item is placed inside a physical letter, envelope, or package.

Use attached when a digital file is added to an email.

Situation	Preferred word	Example
Paper inside an envelope	enclosed	The signed form is enclosed.
Receipt inside a package	enclosed	A receipt is enclosed with your order.
PDF added to an email	attached	The invoice is attached.
File uploaded with a message	attached	Please review the attached report.
Document physically fastened to another item	attached	The label is attached to the box.

Therefore, avoid writing:

• I enclosed the PDF in this email.

A clearer version is:

• I attached the PDF to this email.

Although some people may understand the first sentence, attached matches modern digital communication more accurately.

Enclosed in Physical Spaces

The word enclosed commonly describes spaces with boundaries.

Examples include:

• an enclosed room
• an enclosed balcony
• an enclosed garden
• an enclosed parking area
• an enclosed trailer
• an enclosed playground
• an enclosed stairway
• an enclosed swimming pool

The word may also appear in safety instructions.

For example:

• Do not operate the machine in an enclosed space.

Here, the phrase may refer to a place with limited airflow. The meaning is more specific because safety concerns depend on ventilation.

Therefore, always read the surrounding context. An enclosed space may simply be surrounded, or it may also have poor airflow.

Enclosed in Legal and Property Writing

Property descriptions often use enclosed to explain how land or buildings are divided.

Examples:

• The rear yard is enclosed by a brick wall.
• The property includes an enclosed garage.
• The field is enclosed by fencing on three sides.
• The tenant may use the enclosed courtyard.

Older property records may use inclosed, especially in quotations or transcriptions.

Suppose an 18th-century deed says:

“A parcel of inclosed ground adjoining the road.”

When quoting the record, preserve inclosed. However, a modern explanation should use enclosed:

• The deed refers to a parcel of enclosed land beside the road.

This approach respects the original source without carrying outdated spelling into new writing.

Pronunciation and Part of Speech

The base verb enclose is commonly pronounced with a final z sound.

The related forms are:

Form	Part of speech	Example
enclose	Base verb	Please enclose the receipt.
encloses	Third-person singular verb	The wall encloses the garden.
enclosed	Past tense, past participle, or adjective	The enclosed form is complete.
enclosing	Present participle or gerund	They are enclosing the patio.
enclosure	Noun	The tiger entered the enclosure.

The historical form inclosed was generally intended to carry the same meaning as enclosed. The difference is spelling and modern acceptance, not a major difference in pronunciation or definition.

Common Mistakes With Inclosed and Enclosed

Using Inclosed in Modern Writing

Incorrect in normal modern use:

• The signed agreement is inclosed.

Correct:

• The signed agreement is enclosed.

The first version may be understood, but it looks outdated.

Using Enclose After “Is” or “Was”

Incorrect:

• The receipt is enclose.
• The yard was enclose by a fence.

Correct:

• The receipt is enclosed.
• The yard was enclosed by a fence.

After is or was, you need the past participle enclosed.

Confusing Enclosed With Attached

Less accurate for email:

• The spreadsheet is enclosed in this email.

Better:

• The spreadsheet is attached to this email.

Use enclosed for a physical item inside something. Use attached for a digital file.

Confusing Enclosed With Included

The word included is broader than enclosed.

For example:

• Breakfast is included in the room price.
• A return label is enclosed in the package.

Breakfast is part of the service, but it is not physically placed inside the price. The label, however, is physically inside the package.

Using Enclosure When Enclosed Is Needed

Incorrect:

• The enclosure garden is private.

Correct:

• The enclosed garden is private.

Enclosed describes the garden. Enclosure is a noun.

Misspelling Enclosure

The standard noun is enclosure.

Correct:

• The animals are inside the enclosure.

Avoid inclosure in ordinary modern writing unless you are discussing a historical spelling.

Related Forms of Enclose

Enclose

The base verb means to surround or place inside.

• Please enclose a copy of your receipt.

Encloses

This is the third-person singular present form.

• A stone wall encloses the property.

Enclosed

This is the past form, past participle, and adjective.

This noun may refer to a surrounded area or an item included with a letter.

A Real-World Business Example

Consider this sentence in an email:

Please find inclosed the contract you requested.

It contains two problems.

First, inclosed is outdated. Second, a digital contract is normally attached, not enclosed.

A better version is:

Please find the requested contract attached.

A more natural version is:

I’ve attached the contract you requested.

Now consider a printed letter containing a paper contract:

I have enclosed the contract you requested.

In that case, enclosed is accurate because the document is physically inside the envelope.

This example shows why correct word choice depends on both spelling and context.

How to Remember Enclosed

The easiest memory trick is to connect enclosed with enclosure.

An enclosure is enclosed.

Both standard words begin with en-.

You can also ask three questions:

• Is something surrounded by a boundary?
• Is a physical item placed inside a letter or package?
• Am I writing in modern English?

If the answer is yes, use enclosed.

For email files, ask one more question:
