Etymology
The word 'infest' originates from the Latin verb infestare, meaning 'to attack, disturb, or molest'. This verb was built upon the adjective infestus, which signified 'hostile, unsafe, or dangerous'. The core root fest- carries the ancient sense of active enmity or aggression. Over time, the meaning evolved from a general sense of hostile invasion to the more specific modern sense of being overrun by harmful organisms like pests or parasites, capturing the logic of a hostile force moving into a space to occupy it destructively.
