Spelling errors refer to mistakes made while writing or typing a word. These can include misspellings, where letters are omitted, transposed, or added incorrectly; homophones, which occur when words that sound alike but have different meanings and spellings are used interchangeably; and typos, which involve unintentional errors such as hitting the wrong key while typing. Spelling errors can lead to confusion, miscommunication, and even embarrassment if they appear in a public setting.
