Use an ellipsis (. . .) to omit words in quoted sentences or text.
You can replace as many words as you want with an ellipsis as long as the sentence remains grammatically complete. Be careful not to accidentally alter the meaning of a sentence when you use an ellipsis.
Original text:
“Tyrone stopped at the store and bought milk, orange juice, and bread before going home last night. He usually shops twice a week.”
Text with ellipsis:
“Tyrone stopped at the store . . . before going home last night. He usually shops twice a week.”
When an ellipsis ends a sentence, use four dots, one of which is a period.
“Tyrone stopped at the store and bought milk, orange juice, and bread. . . . He usually shops twice a week.”
