When you’re writing business letters, legal papers, or even academic essays, small spelling details can make a big difference. One of the most common confusions writers face is whether to use “inclosed” or “enclosed.”
If you want your writing to look polished, credible, and up to modern standards, you need to understand the difference.
This guide covers everything — history, meanings, examples, and practical tips — so you never second-guess yourself again.
Quick Overview
Here’s the bottom line up front:
- ✅ Enclosed is the correct, modern spelling in nearly every situation.
- 📜 Inclosed is an older spelling you’ll find mainly in historical documents or old literature.
- 🖊 Use enclosed in letters, emails, packaging notes, and legal documents today.
- 📚 Use inclosed only if you’re quoting historical texts or discussing old usage.
Key takeaway: Unless you’re dealing with historical documents, always choose enclosed.
Understanding the Basics
The confusion between inclosed and enclosed is rooted in the history of the English language. Both words come from the verb “to close”, meaning to shut or confine something within.
The difference lies in the prefix:
- En- means “to put into” or “to cause to be in.”
- In- historically served a similar function but fell out of favor as English spelling standardized.
As printing, dictionaries, and grammar rules became more uniform in the 18th and 19th centuries, “enclosed” replaced “inclosed.”
Why it matters:
Using the outdated form can make your writing look old-fashioned or even incorrect in modern contexts. Choosing the right spelling keeps your communication professional and credible.
Origins and Historical Development
The story of inclosed versus enclosed traces the evolution of English spelling itself.
Etymology
- The root word “close” comes from Latin claudere, meaning “to shut.”
- The prefix “in-” in Middle English often had the sense of “within.”
- Over time, “en-” became more common as a prefix for verbs in English, influenced by French after the Norman Conquest.
The Shift
- Before the 18th century, English spelling was far less standardized.
- “Inclosed” appeared in land deeds, letters, and legal records.
- By the early 19th century, dictionaries like Samuel Johnson’s Dictionary and later Noah Webster’s American Dictionary promoted consistent spelling.
- “Enclosed” gradually became the preferred and accepted form in both British and American English.
Fun Fact
The Enclosure Acts in Britain (18th–19th century), which transformed farmland, sometimes used both spellings in official records — a sign of the transition.
Inclosed: Definition and Historical Usage
Inclosed simply means “shut in” or “contained within,” just like enclosed. The difference is not semantic but historical.
Historical Context
- Common in legal deeds and property documents prior to the 19th century.
- Often used in literary works. For example: “The garden was inclosed by a high wall.”
- Found in archival materials such as court records, colonial charters, and historical letters.
Why It Fell Out of Use
- The standardization of English spelling in education and print.
- Adoption of enclosed in government records and dictionaries.
- Gradual disappearance from everyday communication by the early 20th century.
Enclosed: Definition and Modern Usage
Today, enclosed is the universally accepted spelling. It’s the form you’ll see in business, legal, academic, and everyday communication.
Modern Meanings
- Contained or included: “Please find the receipt enclosed with this letter.”
- Surrounded or fenced in: “The park is enclosed by a wooden fence.”
- Closed off from outside elements: “The laboratory is in an enclosed space.”
Common Contexts
- Business Letters & Emails: “Please see the enclosed invoice for details.”
- Legal Documents: “The property described in the enclosed deed…”
- Shipping & Packaging: “User manual enclosed in the box.”
- Architecture: “An enclosed courtyard provided privacy.”
Pro Tip
Most style guides — including APA, MLA, and Chicago Manual of Style — recommend enclosed.
