Commas and dashes are both punctuation marks used to add extra information or parenthetical elements to a sentence. However, they differ in formality and the degree of interruption they create. Let's break down each one:
A comma (,) is a punctuation mark that separates elements within a sentence. When used to add extra information, commas create a gentle pause and indicate that the information is closely related to the main clause. The information set off by commas is usually non-essential, meaning the sentence would still make sense without it.
A dash (β), specifically an em dash, is a punctuation mark that indicates a stronger break in thought than a comma. When used to add extra information, dashes create a more abrupt interruption and emphasize the added information. Dashes can set off essential or non-essential information.
