What does apostophe mean?

apostophe meaning in Urban Dictionary

probably the most butchered punctuation level within the English language. Apostrophes are utilized 1) toindicate contractions, 2) to point control (in some instances), and 3) VERY sometimes to denote a plural (where usually this is for the sentence could be unclear). The employment of an apostrophe inside contraction "it's", (meaning "it is"), yet not in "its", (which will be a possessive) causes issues for most people who did not pass third class.
