The inverted question mark, , and inverted exclamation mark, , are punctuation marks used to begin interrogative and exclamatory sentences or clauses in Spanish and some languages which have cultural ties with Spain, such as Asturian and Waray languages. The initial marks are mirrored at the end of the sentence or clause by the 'ordinary' question mark, , or exclamation mark, .
Inverted marks are supported by various standards, including ISO-8859-1, Unicode, and HTML. They can be entered directly on keyboards designed for Spanish-speaking countries.
Usage
The inverted question mark is written before the first letter of an interrogative sentence or clause to indicate that a question follows. It is a rotated form of the standard symbol "?" recognized by speakers of other languages written with the Latin script. A normal question mark is written at the end of the sentence or clause.
Inverted punctuation is especially critical in Spanish since the syntax of the language means that both statements and questions or exclamations could have the same wording. "Do you like summer?" and "You like summer." are translated respectively as and (There is not always a difference between the wording of a yes–no question and the corresponding statement in Spanish.)
In sentences that are both declarative and interrogative, the clause that asks a question is isolated with the starting-symbol inverted question mark, for example: ("If you cannot go with them, would you like to go with us?"), not This helps to recognize questions and exclamations in long sentences.
Unlike the ending marks, which are printed along the baseline of the text, the inverted marks (¿ and ¡) descend below the line.
History
Inverted marks, simple in the era of hand typesetting, were originally recommended by the (Royal Spanish Academy), in the second edition of the (Orthography of the Castilian language) in 1754 recommending it as the symbol indicating the beginning of a question in written Spanish—e.g. ("How old are you?"; ). The Real Academia also ordered the same inverted-symbol system for statements of exclamation, using the symbols "¡" and "!".
These new rules were slowly adopted; there are 19th-century books in which the writer uses neither "¡" nor "¿".
Outside of the Spanish-speaking world, John Wilkins proposed using the inverted exclamation mark "¡" as a symbol at the end of a sentence to denote irony in 1668. He was one of many, including Desiderius Erasmus, who felt there was a need for such a punctuation mark, but Wilkins' proposal, as was true of the other attempts, failed to take hold.
Adoption
Some writers omit the inverted question mark in the case of a short unambiguous question such as: ("Who comes?"). This is the criterion in Galician and formerly in Catalan. Certain Catalan-language authorities, such as Joan Solà i Cortassa, insist that both the opening and closing question marks be used for clarity. The current IEC prescription for Catalan is not to use the inverted marks.
Some Spanish-language writers, among them Nobel laureate Pablo Neruda (1904–1973), refuse to use the inverted question mark.
It is common on social media to omit the inverted question mark since it saves typing time. Some also use the ending symbol for both beginning and ending, like this: . Others may even use both the opening and closing question marks, but at the end of the sentence, giving or . Given the informal setting, this might be unimportant; however, unnamed teachers see this as a problem, fearing and claiming that contemporary young students are inappropriately and incorrectly extending the practice to academic homework and essays.

Mixtures
It is acceptable in Spanish to begin a sentence with an opening inverted exclamation mark ("¡") and end it with a question mark ("?"), or vice versa, for statements that are questions but also have a clear sense of exclamation or surprise such as: ("And who do you think you are?!"). Normally, four signs are used, always with one type in the outer side and the other in the inner side (nested) (, )
Unicode 5.1 also includes , which is an inverted version of the interrobang, a nonstandard punctuation mark used to denote both excitement and a question in one glyph. It is also known as a "gnaborretni" () (interrobang spelled backwards).
