The question mark ? (also known as interrogation point, query, or eroteme in journalism[1]) is a punctuation mark that indicates a question or interrogative clause or phrase in many languages.
History = In the fifth century, Syriac Bible manuscripts used question markers, according to a 2011 theory by manuscript specialist Chip Coakley: he believes the zagwa elaya (“upper pair”), a vertical double dot over a word at the start of a sentence, indicates that the sentence is a question.[2][3]
