Accidentally or Accidently Said It Wrong? Hidden Truth! 😲

Accidentally is the correct spelling, while accidently is incorrect and rarely used.

Many English learners confuse these two words because the extra “-al-” in accidentally is easy to overlook. Accidentally means “by chance” or “without intention”, as in: “She accidentally dropped her phone.” In contrast, accidently is considered a spelling mistake in most dictionaries and style guides and should be avoided in emails, essays, social media posts, and exams.

People often make this error when writing quickly or relying on intuition, but knowing the correct form can prevent careless mistakes. To make it easier to remember, think of “accidentally” as having the full “-al-” before the “-ly,” which matches the word accidental.

In this article, you will learn the correct spelling, why the mistake happens, common usage examples, and simple tips to never confuse accidentally with accidently, so your writing is always clear, professional, and accurate.

Accidentally or Accidently

“Accidentally” is the correct standard spelling. “Accidently” is a common misspelling.

The correct adverb is accidentally. It means “by accident” or “in a way not planned or intended.” The misspelling accidently likely arises from how we casually pronounce the word, often dropping the “-al” sound.

Examples:

• “I accidentally deleted the important file.” (Correct)
• “She accidentally sent the email to the wrong client.” (Correct)
• “He turned on the light accidently.” (Incorrect – use “accidentally”)

Remember: The adjective is “accidental.” Just add “-ly” to form the adverb: accidental + ly = accidentally.

The Origin of Accidentally

To understand the spelling, we look to the word’s history. “Accidentally” comes from the Medieval Latin word accidentālis, meaning “happening by chance.” This entered Old French as accidentel and then Middle English as “accidental.”

The core noun is “accident,” from Latin accidēns, meaning “a happening” or “chance event.” The “-al” suffix is used to form the adjective (“accidental”), and the “-ly” suffix then forms the adverb (“accidentally”). This “-al” is a crucial linking element. The misspelling “accidently” tries to jump directly from the noun “accident” to an adverb by adding “-ly,” which breaks the standard word-formation rule. The spelling difference exists because spoken language is often faster and less precise than written language. We slur the “-al” sound, leading to the phonetic but incorrect written form.

British English vs American English Spelling

Here’s a key point: both major English varieties agree on this one. There is no difference between British and American English for “accidentally.” The correct spelling is accidentally on both sides of the Atlantic. The incorrect “accidently” is a misspelling in all standard forms of English.

This unity is unlike other classic spelling differences (like colour/color or realise/realize). However, both dialects share other -tal to -tly pronunciation shortcuts, which might fuel the confusion.
