In written language, two asterisks ( ) are used to point a specific part of textual content. They can be utilized for emphasis, to spotlight a key phrase or phrase, or to mark a correction or addition.
For instance, if you happen to needed to emphasise the key phrase “essential” in a sentence, you could possibly write it like this: “That is essential data.” The asterisks would make the phrase “essential” stand out from the remainder of the textual content and draw the reader’s consideration to it.
