What does fattener mean?
Fattener is an uncommon English noun with two closely related uses. Its best-known meaning is an additive or feed given to livestock to make the animals gain weight or fat before slaughter. It may also denote a person or thing whose function is to cause fattening. The term is therefore practical and largely agricultural rather than a general synonym for “fattening agent”: context determines whether it names the material used, the mechanism, or the worker responsible. Modern readers are most likely to encounter it in animal husbandry, feed formulations, and historical descriptions of livestock work. Though its everyday vocabulary value is limited, it illustrates how English can use the suffix -er to turn a verb such as fatten into the name of a substance or worker. It also shows how a precise agricultural term can acquire a broader agentive sense without losing its connection to the original action of making an animal fatter.
