Etymology
The word 'infested' originates from the Latin verb 'infestare', meaning 'to attack, disturb, or haunt'. This verb itself derives from the adjective 'infestus', translating to 'hostile, unsafe', which is built from the intensive prefix 'in-' and a root related to 'festinare' (to hasten), suggesting a pressing, aggressive threat. The semantic journey moved from describing a state of active hostility or warfare to specifically denoting the troublesome overrunning by pests, parasites, or anything undesirable. The '-ed' suffix marks its common adjectival and participial forms in Modern English, describing a state resulting from such an invasion.
