infraction

Etymology

It is borrowed from Latin īnfrāctiō (“a breaking, weakening”),^[2][3][4][5] a noun of action from the past participle of īnfringō (“to break off, damage, bruise”), the source of infringe,^[2][6][7] from in- (“in”) and frangō (“to break”),^[7][8] from Proto-Indo-European *bhreg- (“to break”).^[7] It is also borrowed from Middle French infraction in Barnhart's account,^[9] and Etymonline likewise names the French word, recorded from the 13th century.^[7][2] Merriam-Webster's Collegiate takes it through Medieval Latin.^[10] In Anglo-Norman the noun is recorded only from 1502.^[11]

Earliest recorded meaning

A breach of a law, obligation or right: 1461, in the Rolls of Parliament, according to Barnhart,^[9] with Etymonline, the Shorter Oxford and Merriam-Webster Unabridged also placing it in the 15th century.^[7][3][6] The OED's entry, not fully revised, begins only in 1623,^[2] as do Dictionary.com and Hoad, in the early 17th century.^[12][4]

Semantic evolution

The Latin noun meant a physical breaking,^[7][5] and the OED records that sense in English from 1623, in Cockeram's dictionary.^[2] Its first quotation for a breach of a bond or obligation is 1673, from William Temple,^[2] but other sources put that sense first, in the 15th century.^[9][7][3] Johnson (1755) gave "the act of breaking; breach; violation" and quoted Waller on "the infraction of my former faith", and his 1773 edition specified the violation of a treaty.^[13] Medicine took the word up for a kind of fracture, with a first quotation of 1882.^[2][6] The modern word usually concerns a law, rule or agreement,^[14][15] and is often applied to minor offences.^[6][16] The related verb infract, from the 1560s, is now archaic.^[7]
