What does extremely mean? Extremely means to a very great degree—exceedingly. Instead of saying I’m very very tired, you could say I’m extremely tired.

It emphasizes or intensifies the meaning of the adjective and indicates that its level is far beyond the ordinary. Example: At some times during the winter, it gets so extremely cold here that it’s dangerous to go outside for more than a minute.
