If you have seen both inclosed and enclosed, the difference can look like a spelling mistake. Both forms express the basic idea of putting something inside, surrounding it, or closing it in.
For modern US English, the practical choice is enclosed. Inclosed is recorded as a less common variant, but it is unusual in contemporary writing.
Quick Answer
Enclosed is the standard choice for modern US English.
Use it in schoolwork, business writing, letters, applications, reports, and everyday communication:
- Please review the enclosed document.
- The patio is enclosed by glass panels.
- I enclosed a copy of the receipt.
Inclosed has the same basic sense but is much less common. It may appear in older books, historical documents, or preserved quotations.
Why People Confuse Them
Inclose and enclose are forms of the same basic verb. Their past forms are inclosed and enclosed.
The spellings also sound essentially the same. Older writing can add to the uncertainty because inclosed may be genuine historical usage.
Key Differences At A Glance
| Context | Best Choice | Why |
|---|---|---|
| Modern US business writing | enclosed | Familiar and standard today |
| School or professional writing | enclosed | Matches current common usage |
| Describing a surrounded space | enclosed | Natural modern form |
| Item inside a letter or package | enclosed | Standard contemporary wording |
| Quoting an older document exactly | inclosed | Preserves original spelling |
| Reading historical writing | inclosed may appear | It is a recognized older variant |
Meaning and Usage Difference
The two forms do not normally express different meanings. Enclosed can mean surrounded on all sides, contained within a space, or placed inside an envelope or package.
“The garden is enclosed by a fence” describes a bounded area, while “I enclosed the receipt with the letter” describes an item placed inside physical correspondence.
Inclosed can carry these same basic meanings. The important distinction is current usage, not a separate everyday meaning.
Tone, Context, and Formality
Enclosed works across ordinary, professional, and formal contexts:
- The enclosed form must be signed.
- The children played in an enclosed courtyard.
Inclosed can sound old-fashioned because contemporary readers encounter it far less often. It has no separate modern meaning.
Which One Should You Use?
Choose enclosed unless you have a specific reason to preserve the older spelling.
Use enclosed for business letters, schoolwork, applications, reports, correspondence, and descriptions of physical spaces or mail.
Use inclosed mainly when reproducing or discussing wording that originally used that form.
For digital files, modern readers often expect attached rather than enclosed. That is a separate medium-based choice.
When One Choice Sounds Wrong
In a modern sentence such as “Please review the inclosed form,” inclosed may look like a spelling error because readers normally expect enclosed.
The same applies to “The patio is inclosed by glass.” The meaning is clear, but the spelling feels unusual in contemporary US English.
Prefer:
- Please review the enclosed form.
- The patio is enclosed by glass.
If an old quotation contains inclosed, preserving the original spelling may be appropriate.

FAQs
Is “inclosed” a correct word?
Yes, “inclosed” is a recognized variant, not a meaningless typo. It is recorded as a less common form of enclose. However, enclosed is the normal modern choice, so use it unless you are preserving older wording.
Should I use “inclosed” in a business letter?
No. Use “enclosed” in contemporary business letters, applications, and other formal writing. For example, “Please find the enclosed form” uses the familiar modern spelling and avoids making a reader wonder whether the unusual form is intentional.
Do “inclosed” and “enclosed” mean the same thing?
Yes, their basic meanings overlap. Both can describe something surrounded, contained, or placed inside an envelope or package. The main difference is modern usage: enclosed is standard and familiar, while inclosed is much less common.
Is “enclosed” a verb or an adjective?
It can be either, depending on the sentence. In “I enclosed the receipt,” it is the past-tense verb form. In “the enclosed receipt,” it works as an adjective describing the receipt.
Why do I see “inclosed” in older documents?
“Inclosed” survives in older writing because that spelling was historically used for the same basic word. Historical documents, quotations, and reproductions may preserve it. Seeing it there does not mean it is the usual spelling for contemporary American writing.
Are “inclosed” and “enclosed” pronounced differently?
No practical pronunciation distinction separates them in ordinary English. Both forms are pronounced essentially the same way, so the difference is mainly visible in writing. That is why readers can recognize the meaning even when the older spelling appears.
Conclusion
For modern US English, enclosed is the form to use.
Inclosed is a genuine recorded variant with historical use, but it is much less common today. It can still appear in older texts or preserved quotations, where keeping the original spelling may matter.
For a current letter, report, application, assignment, or everyday message, choose enclosed.
