gylt

Old English gylt meant 'crime,' 'sin,' 'fault,' and 'fine' — all at once. It was a legal and moral term, used in the laws of King Ine of Wessex in the late 600s to describe both the offense and the penalty. A gylt was something you did wrong and the payment you owed for doing it. Crime and punishment were the same word.

The origin is a puzzle. The Oxford English Dictionary labels it 'of obscure origin.' Some linguists, including Calvert Watkins, have proposed a connection to Old English gieldan, meaning 'to pay' or 'to yield' — the same root that gives us the modern word 'yield.' If true, guilt was originally a debt. You committed an offense and you owed something. The feeling we call guilt would then be the sensation of owing.

The word's meaning migrated inward around the same time as fear and shame. In Old English, gylt was external — a crime committed, a fine assessed. By Middle English, guilt was also the feeling of having done wrong, even without a court or a fine. The 14th-century poem Piers Plowman, attributed to William Langland, used the word in both senses — legal liability and private torment.

The legal meaning never fully disappeared. 'Guilty' in a courtroom and 'guilty' in a confession booth are the same adjective with the same spelling, but they describe different things — one is a verdict, the other is a feeling. English never separated them. Every guilty verdict carries the emotional residue, and every guilty conscience echoes the courtroom.
