How should I read words like Alice's, George's, Charles's ?
And another one---why it is Charles's instead of Charles' ?
When a word ends with an "s", and I want to use it in the possessive form, how should I change it? Should I add 's or just ' ? :?:

How should I read words like Alice's, George's, Charles's ? The apostrophe s requires that you read it as an additional syllable.
And another one---why it is Charles's instead of Charles' ?
When a word ends with an "s", and I want to use it in the possessive form, how should I change it? Should I add 's or just ' ? :?:

Either usage is acceptable. I prefer to use apostrophe s. Look here. Possessive Form of Singular Nouns Ending with S - Writing - English Rules
