Auxesis (Greek: αὔξησις, aúxēsis) is the Greek word for "growth" or "increase". In rhetoric, it refers to varying forms of increase:

• hyperbole (overstatement): intentionally overstating a point, its importance, or its significance^[1][2][3]
• climax (ascending series): a series of clauses of increasing force^[4]
• amplification (rhetorical increase): extension or exaggerated, needless repetition of arguments to emphasize the point
