Etymology

The etymology of the word is obscure, and developed its modern spelling from the Old English form gylt "crime, sin, fault, fine, debt", which is possibly derived from Old English gieldan "to pay for, debt". Because it was used in the Lord's Prayer as the translation for the Latin debitum and also in Matthew xviii. 27, and gyltiȝ is used to render debet in Matthew xxiii. 18, it has been inferred to have had the primary sense of ‘debt’, though there is no real evidence for this.

Its development into a "sense of guilt" is first recorded in 1690 as a misuse of its original meaning. "Guilt by association" is first recorded in 1941.

"Guilty" is similarly from Old English gyltig, itself from gylt.
