What does babbitt mean?
Babbitt is a soft, silvery alloy, typically based on tin or lead with additions of copper and antimony, prized for its low-friction properties and its ability to embed debris without scoring a shaft. Named after the American inventor Isaac Babbitt, who patented it in the nineteenth century, it became the classic lining material for plain bearings in engines, turbines, and machinery, where it is cast or bonded into place and can be reworked by scraping. Separately, the word took on a second life through literature: after Sinclair Lewis's 1922 novel 'Babbitt', whose protagonist is a prosperous but spiritually empty realtor, 'babbitt' came to denote any complacent, convention-bound, materialistic member of the business class. In technical contexts the term remains current among engineers, while the figurative sense survives chiefly in literary and cultural commentary, carrying a distinctly pejorative charge that mocks uncritical pursuit of respectability and possessions.
A soft antifriction alloy, typically tin or lead combined with copper and antimony, used to line plain bearings.
"The engine's crankshaft bearings were relined with fresh babbitt during the rebuild."
Often called 'babbitt metal' in engineering literature.
A complacent, materialistic, conventionally minded businessperson, modeled on the protagonist of Sinclair Lewis's 1922 novel.
"He lived like a perfect babbitt, prizing Rotary Club luncheons over any genuine passion."
Literary and pejorative; rarely used outside discussions of Lewis's satire.
The plural applies mainly to the figurative sense when referring to multiple such people; in technical use, quantities of the alloy are usually described by mass or batch rather than counted.
"The novel's success turned 'babbitts' into shorthand for a whole class of smug American businessmen."
One man's name gave the world both a metal that keeps engines turning smoothly and the very symbol of the smug, status-obsessed American businessman.

Etymology of babbitt
The alloy takes its name from Isaac Babbitt, an American inventor who patented an antifriction metal composition in 1839; the material was long marketed as 'Babbitt's metal' before the surname alone became generic. The figurative sense derives from George F. Babbitt, the title character of Sinclair Lewis's satirical 1922 novel 'Babbitt', which won Lewis wide acclaim and contributed to his later Nobel Prize in Literature. Because the two senses arise independently — one eponymous from metallurgy, one literary — they share only the name itself.

How babbitt is actually used
As a materials term, 'babbitt' is standard technical usage among machinists and engineers. As a label for a person, it is literary and somewhat dated; it carries a strongly pejorative, satirical connotation and is largely understood in reference to Lewis's novel rather than used in everyday speech.
Easily confused with babbitt
'Rabbit' is a common burrowing mammal of the family Leporidae, whereas 'babbitt' is either an industrial bearing alloy or a term for a conventional, materialistic businessman — the similar sound invites confusion but the meanings are entirely unrelated.
