Inverted question and exclamation marks
Inverted question (¿) and exclamation marks(¡) 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) or Catalan.
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 fully above the line in a sentence, the (¿) and (¡) are placed about halfway below the line.
