I just wanted to ask you if at the end of a formal letter you are suppose to use a capital "S" when using Sincerely or a captail "F" when using Faithfully. Please can you help me with this query.
I'd just like to add that the first word only is capitalized, so "Yours truly," and "Sincerely yours,". "Sincerely" can go before or after "yours", and is often used by itself (no "yours") to make the tone slightly less formal, but it's always "Yours truly/faithfully". "Faithfully" is not really common in North America.
