Contraction

Is a shortened form of a phrase.It is used in informal speech and is made by taking two words(one of which is a verb)and dropping a letter or letters from either or both of the words,then using an apostrophe to replace the letter dropped.Note that the rule is different in the case of will not,which also drops the letters -ill in the word will and replace them with -o.
