guilt

Etymology 1

From Middle English gilt, gult, from Old English gylt (“guilt, sin, offense, crime, fault”), of obscure origin. Perhaps connected with Old English ġieldan (“to yield, pay, pay for, reward, requite, render, worship, serve, sacrifice to, punish”), whence yield.

noun

1. Responsibility for wrongdoing.
2. (law) The state of having been found guilty or admitted guilt in legal proceedings.
3. The regret of having done wrong.
   Appropriate guilt is experienced when we actually do something objectively wrong—for example, exploit another, betray a trust, and so on. […] Inappropriate guilt occurs from believing a lie and is resolved by an application of the truth. 2018, Timothy R. Jennings, The Aging Brain, page 158
