in the flesh; without involving anyone else
"I went there personally"
"he appeared in person"
In a personal manner.
"I personally felt embarrassed when he mentioned my mistake in front of everyone."
In plain English: When you do something yourself rather than letting someone else do it for you.
"I personally prefer to walk home in the evening."
Usage: Use personally to indicate that you are speaking from your own individual perspective or doing something yourself rather than through an agent. Avoid using it simply to mean "privately," as that usage is often considered incorrect in formal contexts.
The word personally comes from Middle English and is formed by adding the suffix "-ly" to the adjective "personal." It entered modern English with the same meaning it held centuries ago, describing actions done directly by an individual rather than through others.
