Etymology

It is inherited from Middle English sinne, inherited from Old English synn (“wrongdoing, offence, misdeed”),[2][3][4] from Proto-Germanic *sundjō,[3][2] which also gave Old Frisian sende, Old Saxon sundia, Dutch zonde, German Sünde and Old Norse synd.[2][3][4] It is probably related to Latin sōns (“guilty”),[3][5][6] which Barnhart explains as a specialized use of the old present participle of esse (“to be”);[3] according to Watkins, as cited in Etymonline, the notion was “it is true”, that is “the guilt is real”, from PIE *es-ont-, the participle of Proto-Indo-European *es- (“to be”) (compare sooth).[2] The verb is from Old English syngian, from the same source as the noun.[3][2][4]

Earliest recorded meaning

An act that breaks divine law, and wrongdoing in general: about 825 in the OED, before 830 in Barnhart.[7][3] Old English synn also meant injury, enmity and guilt.[2]

Semantic evolution

A pity or shame (“it's a sin”) is from about 1300 and is still colloquial, especially in Scotland.[7] A breach of a standard of taste or propriety is from 1780.[7] Ugly as sin and similar phrases date from the early 17th century.[7] Sin-eater, one paid to take on a dead person's sins by eating food over the corpse, is from the 1680s,[2] and to live in sin, to live together unmarried, from 1838.[2][7] In Shetland and other Scots dialects sin also meant blame.[8]
