Forms

infestātiō f (genitive infestātiōnis); third declension[1]

Etymology

It is formed from Latin īnfēstō (“to attack, molest”) + -tiō,[1][2] the verb being from Latin infestus (“hostile”).[2]

Earliest recorded meaning

The TLL records it from Frontinus on, who uses it of vexatious or harmful activity;[3][4] Köbler dates Frontinus to about AD 100.[2]

Semantic evolution

In Tertullian it means hostility and persecution,[4][5] and the TLL records the plural from Cyprian on.[3] In Christian and medieval Latin it named harassment by people or demons, molestation and armed attack,[6][7][8] and in legal use the harassment of someone by lawsuits or force.[9] Medieval writers also used it of a disease and its attacks.[10][8]

English took it over in the early 15th century as infestation, through Old French.[11]
