Incorrect spelling, explanation: some learners of English can confuse the word holy with holly, meaning a shrub or a tree with shiny evergreen leaves and red berries. However, the word hollyday does not exist and therefore, this is a misspelling. It means that the users of English should memorize that the only correct form is holiday, not hollyday.

Correct spelling, explanation: the word comes from Old English, stemming from two parts of the speech, the adjective holy and the noun day which literally means a special, sacred period of time. In the 12th century, it was known as haliday, and as the form used today holiday first surfaced in the 1500s. Considering the origin of the language, we conclude that holiday is spelled correctly, whereas hollyday is not.
