Correct spelling, explanation: both CC’d and CC’ed are commonly used and considered correct in the English language. They are both abbreviations of the word carbon copied or courtesy copied and refer to the practice of sending a copy of an email or document to additional recipients besides the primary recipient. In more formal or professional writing, CC’d is generally more widely accepted and preferred. The apostrophe before ed indicates that the word has been shortened by omitting the letters arbon copi.

Correct spelling, explanation: CC’ed is the past tense and past participle of the verb CC (carbon copy) or ccing. It is commonly used in the context of email communication and refers to the act of sending a copy of an email to additional recipients, apart from the primary recipient. The term originates from the use of carbon paper in older typewriters to make duplicate copies of documents. Both CC’d and CC’ed are acceptable and widely used forms. The difference lies in the style of punctuation, where one uses an apostrophe before ed (CC’d) and the other uses an apostrophe after cc (CC’ed).
