used to denote a clause within an actual sentence (or sometimes inbetween what some would consider as othrewise *two* seperate sentences, though are one due to its '..'-connection) for a briefer amount of time than a full ellipsis(…, ...) denotes(example1). Also used sometimes before a question-mark{?} when what the someone is saying seems to be trailing-off so-to-speak, though can be substitued by ...(example2).

Just like a regular ellipses, but you don't want the person receiving the text to know you think that way. They might just think its a typo.
