Yours sincerely or Your's sincerely? I've been taught to use the former but my tutor said that by not adding the apostrophe, would mean like pluralizing the word.

Question

Yours sincerely.

"Your's" is incorrect because the word should never have an apostrophe. "Yours" is the only correct spelling and it's possessive and never plural. 

e.g.  It is yours sincerely. / It is sincerely yours.

So I got a red apostrophe between the r and s for nothing?

anonymous · Answer

Yup.  For the singular possessive pronouns, it's (short for "it is") -- mine, yours, his, hers, its.  The plural set is ours, yours, theirs.  (Ex: The book is mine, the book is yours, the books is hers, . . . etc.)  

No apostrophes anywhere.  Only nouns take apostrophes to show possession.  

Note that "yours" can be singular or plural, just as "you" can be.  "Sincerely yours" is short for something like "I am yours, sincerely" or "I am sincerely yours," I suppose.
