The phrasal verb "throw off" is more commonly used in informal contexts than in formal speech or writing. It has a variety of meanings depending on the context: it can refer to discarding or getting rid of something, as in "throw off old habits"; confusing or derailing someone, as in "His unexpected comment threw me off during the presentation"; or even emitting something, such as heat or light, as in "The lamp throws off a lot of heat." Its versatility makes it a useful phrase in conversational English and everyday situations, often implying a sense of casual or unexpected disruption or departure from the norm. In a more literal sense, it might also describe the action of physically shaking something off one's body or clothes. However, due to its informal nature, it is less likely to be used in professional or highly technical contexts.
