Because spelling errors may lead to misunderstandings in terms of context and communication, knowing how to spell words correctly is integral, especially in academic writing. One of the main reasons why these errors can occur is due to similar spelling variations in other languages and the lack of alignment between pronunciation and spelling. A very common spelling mistake occurs with the word “calendar.” The following article focuses on all the aspects you need to know about it.

The correct spelling of “calendar”

The word “calendar” functions as a noun and as a verb, and has only one correct spelling. The word is derived from the Latin language,“calendarium,” which translates to “account book,” and from the old French word “calendier,” meaning “to list.” It holds the meaning of a register of days arranged in a tabular system, covering one whole civil year, or refers to the systematic listing of items, objects, and activities in modern English. In British English, the noun “calendar” also refers to a catalogue of universities. When used as a verb, “to calendar” refers to the entry of an event or activity in the systematic tabular register in the sense of “to book an appointment.”

Incorrect spelling


The most common mistake occurring in the spelling of “calendar” is the spelling of it with an “e” at the end instead of an “a.” This is common due to the phonetic similarity between both versions. Until the 17th century, the correct spelling of the word was “calender,” describing a machine that pressed materials. Eventually, the spelling was changed to “calendar” to differentiate the tabular register system of a civil year from the pressing machine “calender.” Therefore, the sound-based spelling error is a common occurrence. Additionally, several other languages still spell the word with an “e” at the end, which may also lead to making this common spelling mistake.
