Etymology

Origin of valiant

First recorded in 1275–1325; Middle English valia(u)nt, from Anglo-French; Middle French vaillant, present participle of valoir “to be of worth,” Latin valēre; -ant

Explanation

It was pretty courageous of the automaker Plymouth to name a car the "Valiant" in the 1960s and 70s because that term usually refers to a hero or describes a really determined, or valiant, effort that doesn't end well. Synonyms for valiant include "heroic" and "courageous," so it isn’t surprising that those who serve in the military often are called valiant. The 14th-century French origins of the word are "bold" or "of worth," which makes the adjective valiant a good one for describing ordinary people who put all they have into something, making their efforts valiant, even if they fail. The Plymouth Valiant, by the way, was considered a strong and successful car, though valiant usually refers to people.
