An ellipsis (...) is three dots used for a pause or to show
that words have been left out.
Examples:
A credit card
stolen in London was used to pay for a Chinese meal five hours later...in Bangkok.
(pause for effect) The brochure
states: "The atmosphere is tranquil...and you cannot hear the
trains." (words omitted)
Interactive example:
"The defendant addressed the guard...and
left quietly." [show me the ellipsis]
