    * 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".
