Etymology tree
Forms
īnfringō (present infinitive īnfringere, perfect active īnfrēgī, supine īnfrāctum); third conjugation[1]
Etymology
It is from Latin in- + frangō (“to break”).[2][1][3] De Vaan lists ⟨īnfringere⟩ among the compounds of ⟨frangō⟩ (from Plautus on), which he derives from Proto-Indo-European *bʰr-n-ǵ- (“to break”), cognate with Gothic 𐌱𐍂𐌹𐌺𐌰𐌽 (brikan, “to break”).[4]
Earliest recorded meaning
De Vaan dates it from Plautus;[4] the OLD's early examples include Terence, whose character complains that someone dealt him more than five hundred punches.[2]
Semantic evolution
It is to break or shatter, as Lucretius' boars staining broken weapons with their blood, and also to bend, as an oar that looks broken in water.[2] Cicero uses it of breaking up the rhythm of a sentence.[2] It came to mean to weaken or impair, as Propertius' Venus who can break the strength of heroes, and to temper or reduce: Celsus speaks of fever that has abated, Tacitus of reduced taxes.[2] Of power and persons it is to break, crush or make relent: Juno will not rest, “not broken by Jupiter's command or the fates”, and Cicero speaks of a spirit broken by calamity.[2] It also means to foil an attempt.[2]
Church Latin has it for infringe upon, break.[5] English infringe (mid-15th century), “to violate”, is from it.[6]
