To write a correct sentence, you must always remember three main rules:

  • It must begin with a capital letter.
  • It must contain a subject and a predicate.
  • It must end with proper punctuation (a period ., question mark ?, or exclamation mark !).
Incorrect — Sentence Fragment:

Who is running? There is no clear subject, no capital letter, and no final punctuation.
