Language errors refer to mistakes made in speaking or writing that can affect clarity and understanding. These errors can include grammatical mistakes, such as incorrect verb tenses or subject-verb agreement, as well as spelling and punctuation errors. They can occur in any language, including English, Spanish, or Mandarin, and can be made by both native speakers and learners. Common types of language errors include typos, which are unintentional mistakes in typing, and malapropisms, where a word is mistakenly used in place of a similar-sounding word. These errors can lead to confusion or miscommunication, highlighting the importance of proofreading and practicing language skills for effective communication.
