An ellipsis is a row of three full stops, used to show that words have been left out. How it looks depends on where it is in the sentence:
The beginning of a sentence
There should be no space between the ellipsis and the word.
…We are aware that each country is unique.
In the middle of a sentence
There should be single spaces before and after the ellipsis.
We are aware that each country … is unique.
The end of a sentence
There should be no space before it and no full stop.
We are aware that each country is unique…
If this is in a quotation, the sentence can be closed by a full stop after the quotation mark
“We are aware that each country is unique…”.
