Part of a formal or business letter consisting of brief words or abbreviations as notations.
“R.S.V.P.” (Répondez s’il vous plaît) - French for “Please reply.”
The use of this notation indicates that the writer expects the recipient to contact the writer with a “yes” or “no” response to the invitation extended in the body of the letter. Often a corresponding address and/or phone number is printed directly below this notation.
“cc:” (carbon copy) - These initials are followed by a name or column of names, indicating those people to whom a copy of the letter is being sent to. (One-sided inked carbon paper slipped between two pieces of paper was once the method used for duplicating copies of correspondence, hence use of the word "carbon" in this notation).
“encl.” (enclosure) - Indicates that something else accompanying the letter is enclosed.
“PL/rm” (initials of persons) - Indicates that a person typed or even composed a letter on behalf of someone else. The capitalized initials are those of the sender of the letter (Paul Lazarman). The lower-case initials are those of the person who typed or composed the letter (Rachel McDonald) on behalf of the sender. The most common use for this notation is for situations where an administrative assistant composed and/or typed the final version of a letter that was dictated by his/her boss.
