What Does Inclosed or Enclosed Mean?
The expression Inclosed or Enclosed usually refers to a spelling question rather than two equally acceptable modern words. Today, enclosed is the standard spelling used in English.
The word enclosed means something that is:
- placed inside another object
- surrounded by a boundary
- included with a letter, package, or document
- shut in or protected by walls, fences, or covers
For example:
- The receipt is enclosed with your order.
- The garden is enclosed by a wooden fence.
- Please find the signed agreement enclosed.
Common situations where enclosed is used include:
- Business letters
- Legal documents
- Shipping notices
- Emails with attachments
- Property descriptions
Is “Inclosed” Correct?
The short answer is not in modern English.
Although inclosed appeared in English centuries ago, it is now considered an obsolete or archaic spelling. Modern dictionaries, style guides, schools, publishers, and businesses overwhelmingly prefer enclosed.
You may still encounter inclosed in:
- historical letters
- nineteenth-century books
- archived legal records
- older religious texts
- classical literature
Outside of historical quotations, using inclosed may appear outdated or incorrect.
Examples:
Incorrect: The documents are inclosed for your review.
Correct: The documents are enclosed for your review.
Another example:
Incorrect: Please see the inclosed invoice.
Correct: Please see the enclosed invoice.
Therefore, unless you are reproducing historical writing exactly as it originally appeared, always choose enclosed.
What Is the Correct Spelling?
The correct modern spelling is enclosed.
It comes from the verb enclose, which means to surround, include, or place something inside another object.
Remember these important points:
- Enclosed is accepted in modern English worldwide.
- It appears in dictionaries, grammar books, and professional writing.
- It is suitable for academic, legal, and business communication.
- It is preferred in both American and British English.
Examples:
- The application form is enclosed.
- A photograph was enclosed with the letter.
- The playground is enclosed by a tall fence.
- The warranty card is enclosed inside the package.
- The property is enclosed by stone walls.
Difference Between the Two Spellings
| Feature | Inclosed | Enclosed |

| Professional Writing | Not recommended | Recommended |
| Academic Writing | Avoid | Correct |

| Common in Modern English | No | Yes |

The main difference is historical rather than grammatical. Both forms originally conveyed the same meaning, but enclosed replaced inclosed over time and became the accepted standard.

Why Do People Make This Spelling Mistake?
Several factors contribute to confusion between inclosed and enclosed.
Pronunciation Confusion
The prefixes en- and in- often sound similar in rapid speech, making them easy to confuse.
Historical Spellings
Older books and letters frequently used inclosed. Readers may mistakenly assume it is still standard.
Typing Mistakes
Fast typing can lead people to substitute in- for en-, especially because both prefixes exist in English.
Phonetic Spelling
Some writers spell words based on how they sound rather than how they are standardized.
Similar-Looking Words
Many English words begin with in-, such as:
- include
- increase
- indicate
- inform
This pattern sometimes causes writers to choose inclosed by analogy.
Memory Errors
People may remember seeing inclosed in an old document without realizing it represents an earlier spelling.
Regional Influence
Some historical British publications retained inclosed longer than modern English does, which can occasionally create confusion when reading archived materials.
Origin and Etymology
The word enclosed comes from the verb enclose, which entered English through Old French.
The prefix en- means “to put into” or “to cause to be within,” while the root relates to closing or shutting something.
Historically, English spelling was far less standardized than it is today. During the seventeenth, eighteenth, and early nineteenth centuries, writers sometimes used both enclose and inclose, along with enclosed and inclosed.
As English spelling became standardized through dictionaries, educational systems, and publishing practices, enclose and enclosed gradually became the accepted forms. Today, inclosed survives mainly in historical documents and literary archives.
