What is the nuance of the word "undertake"? How is it different from just "do"? I couldn't find good answers looking in web dictionaries. Then I tried to ask to AI service called "Chat GPT" which I got to know recently. Would you kindly comment if the following AI answer is correct or not? Cause the provider of this service says that it may occasionally generate incorrect information and I have to take responsibility to check. Free AI service Chat GPT answers; The word "undertake" typically means to take on or accept a task, duty, or responsibility, often with a sense of commitment or dedication. It can also mean to embark on or begin a new venture or project. In this sense, it is similar to the word "do" in that it refers to performing an action or task, but "undertake" often connotes a more formal or serious commitment to the task at hand. For example, you might say "I will do the dishes" to indicate that you will wash the dishes that are currently in the sink. On the other hand, you might say "I will undertake the task of reorganizing the garage" to indicate that you are willing to put in the effort and time to complete a more significant and involved project. In general, "undertake" is more formal and serious than "do," and it is often used in contexts where the task at hand is of significant importance or requires a great deal of effort and dedication.
