What does undergone mean?
Undergone is the past participle of undergo and describes something that has been experienced or endured. It commonly appears with have, has, or had: a region “has undergone a sharp rise in temperatures,” or a person “had undergone surgery.” The word often suggests an unpleasant, difficult, or significant experience, though it can also refer to a positive change. It may also function as a participial adjective, as in “the loss undergone by the community.” Undergone is not the finite past-tense form: underwent serves that role, while undergone serves as its past participle. Its usefulness lies in conveying that an experience or process has already taken place, often with a sense of consequence or endurance. In formal writing, it provides a precise, slightly formal alternative to more general verbs such as experienced, suffered, and endured.
The past participle of undergo, used with have, has, or had to express that an experience or process has been completed or undergone.

Where does undergone come from?
Undergone is the past participle of the English compound undergo, formed from the prefix under and the verb go. Both components are Germanic in origin: under continues Old English under, while go continues Old English gān. The compound developed from the older idea of going under an experience or ordeal, and the modern irregular pair underwent and undergone preserves that historical sense.
