Usage Note: The adjective precipitate and the adverb precipitately were once applied to physical steepness but are now used primarily of rash, headlong actions: Their precipitate entry into the foreign markets led to disaster. He withdrew precipitately from the race. Precipitous currently means "steep" in both literal and figurative senses: the precipitous rapids of the upper river; a precipitous drop in commodity prices. But precipitous and precipitously are also frequently used to mean "abrupt, hasty," which takes them into territory that would ordinarily belong to precipitate and precipitately: their precipitous decision to leave. Many people object to this usage out of a desire to keep precipitate and precipitous distinct, but the extension of meaning from "steep" to "abrupt" is perfectly natural. After all a precipitous increase in reports of measles is also an abrupt or sudden event. In fact, a majority of the Usage Panel now accepts this usage. In our 2004 survey, 65 percent accepted the sentence Pressure to marry may cause precipitous decision-making that is not grounded in the reality of who you are and what you want from life.
