How to spell accidentally

“Accidentally” is spelled with two “c’s,” one “d,” one “t,” and ends with an “a-l-l-y”: a-c-c-i-d-e-n-t-a-l-l-y.

Technically, this word has five syllables (i.e., “ak-suh-den-tuh-lee”), but fluent speakers often pronounce it so quickly that it sounds like four syllables (i.e., “ak-suh-dent-lee”). Although this pronunciation is acceptable and common, the spelling that ends with “t-l-y,” a-c-c-i-d-e-n-t-l-y, is often considered incorrect.

“Accidentally” is an adverb that describes an action as unintentional or inadvertent. Put simply, it describes something as unplanned or happening by chance. For example, you can accidentally set the wrong time on your alarm, or you can accidentally run into your old roommate at the mall.

Accidentally on purpose

“Accidentally on purpose” is a phrase that describes something as being done intentionally but made to appear like an accident (e.g., “She tripped over the rug accidentally on purpose because she wanted a reason to go home”).
