People often forget that “there’s” is a contraction of “there is” and mistakenly say “there’s three burrs caught in your hair” when they mean “there’re” (“there are”). Use “there’s” only when referring to one item. “There’s” can also be a contraction of “there has,” as in “There’s been some mistake in this bill, clerk!”

Remember if you don’t contract “there is” that it also can only be used with something singular following. It’s not “There is many mistakes in this paper” but “there are many mistakes in this paper.”
