Question mark, exclamation mark, colon and semicolon

Any sentence asking a question ends with a question mark. If the author doubts some information or is not sure of it, he or she may put a question mark in brackets after that word to warn the reader: “U 1998-yilda (?) tug‘ilgan”. The exclamation mark is put when a sentence carries strong feeling – joy, surprise, anger – and also when it gives a command, a request or a wish. It is also put after addresses at the start of a sentence said with strong feeling and after word-sentences such as ha, yo‘q, xo‘p, uzr, mayli, xayr, salom. If a thought is said with extremely strong feeling, up to three exclamation marks may be put in a row. The question and exclamation marks sometimes come together (?!).
