when do you use an inverted question mark
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.
Ellipsis The most common form of an ellipsis is a row of three periods or full stops (...) or a precomposed triple-dot glyph (…). The usage of the em dash (—) can overlap the usage of the ellipsis, especially in dialogue. Style guides often have their own rules governing the use of ellipses. For example, The Chicago Manual of Style recommends that an ellipsis be formed by typing three periods, each with a space on both sides ( . . . ). Whether or not an ellipsis at the end of a sentence needs a fourth dot to finish the sentence is a matter of debate; for example, Chicago advises it, but the OxfordWords blog has suggested that a full stop is considered to be paradoxical to an ellipsis used to indicate an incomplete thought, so it is omitted.[2][3]
