personally

You say that you, personally, think or feel something, because you want to admit that other people may disagree with you.

Example: Personally, I feel like I am one of the best workers here.

If you are personally involved or responsible, or if you do something personally, it is you, yourself, as an individual, and not somebody else.

Example: The president is personally responsible for what happened in New Zealand.

If you take something personally, you believe it was meant to hurt you.

Example: He's just in a bad mood, so don't take it personally.

If you know someone personally, you know them and they know you.

Example: Sure, I know of her, but I don't know her personally.

If something is true personally, it is true of your personality and character.

Example: Even though I'm on TV every day, I'm shy personally.
