what is the purpose of a comma in a sentence
Comma The comma is used in many contexts and languages, mainly for separating parts of a sentence such as clauses, and items in lists, particularly when there are three or more items listed. The word comma comes from the Greek κόμμα (kómma), which originally meant a cut-off piece; specifically, in grammar, a short clause.[1][2]
Inverted question and exclamation marks Inverted question marks (¿) and exclamation marks (Commonwealth English) or exclamation points (American English) (¡) are punctuation marks used to begin interrogative and exclamatory sentences (or clauses), respectively, in written Spanish and sometimes also in languages which have cultural ties with Spanish, such as in older standards of Galician (now it is optional and not recommended) and the Waray language.[1] They can also be combined in several ways to express the combination of a question and surprise or disbelief. The initial marks are normally mirrored at the end of the sentence or clause by the common marks (?, !) used in most other languages. Unlike the ending marks, which are printed along the baseline of a sentence, the inverted marks (¿ and ¡) descend below the line.
