When it comes to capitalization after an ellipsis, the answer can depend on the context in which the ellipsis is used.
If the ellipsis appears at the end of a sentence, the word following it should be capitalized. For example: “I was thinking about going to the park… Maybe later.” In this case, ‘Maybe’ starts a new sentence, and thus it is capitalized.
However, if the ellipsis is used within a sentence and not at the end, the word following the ellipsis is generally not capitalized. For example: “I’m not sure what to do… I guess I could ask for help.” Here, ‘I’ does not need to be capitalized because the sentence continues after the ellipsis.
In summary, always capitalize after an ellipsis if it ends a sentence, but do not capitalize if it’s simply showing a pause or omission mid-sentence.
