Upside-down question and exclamation marks

Rare card · No. 70127

The upside-down (also inverted, turned, rotated, or opening) question mark ¿ and exclamation mark ¡ are punctuation marks used to begin interrogative and exclamatory sentences or clauses in Spanish and some languages that have cultural ties with Spain, such as Asturian and Waray. The initial marks are mirrored at the end of the sentence or clause by the ordinary question mark ? or exclamation mark !. Upside-down marks are supported by various standards, including Unicode and HTML. They can be entered directly on keyboards designed for Spanish-speaking countries.
