The upside-down question mark, also known as an inverted question mark, is a punctuation mark used in Spanish and several other languages to denote the beginning of an interrogative sentence. It is written as an upside-down question mark (?) and is placed at the beginning of a sentence, before the subject. For example, in Spanish, the sentence “Cmo ests?” means “How are you?”
The upside-down question mark is important because it helps readers to identify the beginning of a question. It also helps to distinguish between questions and statements, which can be important in languages where the word order is different from English. For example, in Spanish, the sentence “Ests bien?” means “Are you okay?” If the question mark were not upside down, it would be difficult to tell whether the sentence was a question or a statement.
