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. Extremely is the adverb form of the adjective extreme, which means of the highest degree or intensity. Extremely is almost always used to modify (describe) adjectives and almost never verbs. 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.
