Usage notesEdit

  • Regarding the use of singular their, see they.
  • Distinguish “their” from “there” and “they’re”. “Their” signifies ownership. “There” designates a place (compare here). “They’re” means “they are”.
  • This word is an exception of the "I before E, except after C" rule, as the combination of "ei" in the middle of the word is not after a "c".
