Where does pulchritudinous come from?

Pulchritudinous combines the Latin word pulchritūdō, meaning “beauty,” with the adjectival suffix -ous, meaning “full of.” (Pulchritūdō also gives us the noun pulchritude, meaning “physical beauty” and first recorded in the 1400s.) Pulchritudinous began to appear in the early 1700s and gained popularity in the 1800s with American authors who started using the word because it was humorously long and overly complicated.

Pulchritudinous doesn’t sound like it means “beautiful,” and that’s usually precisely why it’s used—to be ironic, facetious, or just silly. Washington Irving employed it in The Crayon Miscellany (1835) alongside other unnecessarily complex words to make fun of an advertisement for ginger ale.

Because there are many shorter, more common words that could be used instead, pulchritudinous is a word most people either don’t know or avoid using so as not to cause confusion. But if you want to get fancy or a bit cheeky, pulchritudinous is a beautiful choice.
