who is credited for introducing a standardized system of punctuation
Punctuation The amount of printed material and its readership began to increase after the invention of moveable type in Europe in the 1450s. As explained by writer and editor Lynne Truss, "The rise of printing in the 14th and 15th centuries meant that a standard system of punctuation was urgently required."[13] The introduction of a standard system of punctuation has also been attributed to the Venetian printers Aldus Manutius and his grandson. They have been credited with popularizing the practice of ending sentences with the colon or full stop, inventing the semicolon, making occasional use of parentheses and creating the modern comma by lowering the virgule. By 1566, Aldus Manutius the Younger was able to state that the main object of punctuation was the clarification of syntax.[14]
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.
