as if with kid gloves; with caution or prudence or tact
"she ventured cautiously downstairs"
"they handled the incident with kid gloves"
Sorrowfully.
"She carefully placed his favorite book on the shelf, her movements heavy with grief and regret."
In plain English: Carefully means doing something with great attention so you don't make mistakes or cause harm.
"She carefully placed the fragile vase on the shelf."
Usage: Use carefully to describe doing something with attention and caution to avoid mistakes, not to express sadness. Do not use it when you mean sorrowfully, which describes an emotional state rather than the manner of an action.
The word carefully comes from the Middle English term carfulli, which was derived from an Old English root meaning "diligently." It entered modern usage by adding the suffix -ly to the adjective careful to describe how an action is performed.
