Have you ever come across the words inclosed and enclosed and wondered if they mean the same thing? At first glance, the two spellings look very similar, which makes it easy to assume that both are correct. However, when writing an email, letter, or professional document, choosing the wrong spelling can make your writing look outdated or inaccurate.
The confusion exists because inclosed was once used in older English, while enclosed has become the standard spelling in modern usage. As a result, many writers are unsure which form they should use today.
In this guide, we’ll break down the difference between inclosed vs enclosed, explain their history, show real-world examples, and help you understand which spelling is correct in modern English.
What Is the Difference Between Inclosed and Enclosed?
The short answer is simple:
| Word | Status | Modern Usage |
|---|---|---|
| Inclosed | Archaic/Old-fashioned | Rarely used today |
| Enclosed | Standard English | Correct and widely accepted |
Today, enclosed is the preferred spelling in business communication, academic writing, emails, legal documents, and everyday English.
Why Are People Confused?
The confusion comes from historical spelling variations.
Centuries ago, English writers sometimes used prefixes interchangeably. Words beginning with en- occasionally appeared as in-. Therefore, “inclosed” was once an accepted alternative spelling.
However, language evolves. Over time, enclosed became the standard form, while inclosed gradually disappeared from modern usage.

Real-Life Example: A Job Application Mistake
A job seeker submitted applications to multiple companies. In their cover letter, they repeatedly wrote:
Please find my resume inclosed.
Although recruiters understood the intended meaning, some hiring managers viewed the spelling as outdated and potentially incorrect.
The applicant later revised the phrase to:
Please find my resume enclosed.
After updating their application materials, their documents looked more professional and aligned with modern business standards.
This example highlights an important lesson. Even when a word has historical legitimacy, modern readers expect contemporary spelling conventions. Using standard forms improves clarity, professionalism, and credibility.
In professional environments, small language choices can influence first impressions. Recruiters, editors, professors, and clients often notice spelling details. Therefore, choosing enclosed instead of inclosed helps ensure your writing meets current expectations.
The goal of communication is clarity. Since modern audiences recognize enclosed immediately, it remains the safest and most effective choice.
