What does bloodsucker mean?
A bloodsucker is, literally, an animal that feeds on the blood of other living beings — leeches, ticks, mosquitoes, and vampire bats all fall under this description. Figuratively, the word is applied to people who exploit others ruthlessly, especially for money: predatory lenders, unscrupulous landlords, corrupt officials. In this figurative use it is strongly pejorative and informal in register, expressing contempt rather than neutral description. The word's power comes from its visceral imagery — comparing a person to a creature that drains blood frames exploitation as something bodily and parasitic. Related terms such as leech and parasite carry similar meanings, but bloodsucker tends to suggest active, aggressive predation rather than passive dependence. It remains a vivid staple of political rhetoric and everyday invective.

Etymology of bloodsucker
Bloodsucker is a compound of 'blood' and 'sucker', formed from native Old English elements; 'blood' derives from Old English blōd, and 'sucker' from 'suck', traceable through Middle English to Old English sūcan. The compound has been used since at least the early modern period to describe blood-feeding animals, with the figurative sense for exploitative people developing later.
