In an official manner; according to official rules or regulations.
"The new policy will not be officially implemented until the next fiscal year begins."
In plain English: Officially means something is true because an authority has said so and recorded it.
"She officially accepted her new job yesterday after signing the contract."
Usage: Use this adverb when describing actions that comply with formal authority, such as stating someone is officially recognized by the government. It emphasizes adherence to established rules rather than personal opinion or informal agreement.
The word officially comes from combining the adjective official with the suffix -ly to form an adverb. It entered English directly from Latin through French without a significant shift in its core meaning of being authorized or formal.
