Three dots in a row are called ellipsis and can be used to signify that something is missing. It is mainly useful in dialogue. For example:
"I wonderâŠ" said Harry.
The ellipsis suggests that Harry is thinking of something else.
Avoid using ellipsis to end sentences.
Use the semi-colon to link two connected clauses. For example:
I have lots of homework; I canât go out tonight.
