Today's word is crucible, Spelled C R U C I B L E Crucible is a noun. A crucible, in the words literal use, is a pot in which metals or other substances are heated to a very high temperature or melted. But crucible is more often encountered in figurative use, referring to a difficult test or challenge, or to a place or situation that forces people to change or make difficult decisions. Here's the word used in a sentence from Deadline by Matt Grober. The original film follows four married couples, close friends who reunite once a year for a week long vacation together. On the surface, the retreat is meant to help them relax and reconnect, but it quickly becomes a crucible, examining the cracks in their relationships. Unless you're studying Arthur Miller's the Crucible in school, it may not be crucial to learn the story behind the word crucible. But it can't hurt. Crucible looks like it should be closely related to the Latin combining form cruc C R u c, meaning cross. However, unlike the word crucial, it isn't. It was forged instead from the medieval Latin crucibulum, a noun for an earthen pot used to melt metals. And in English it first referred to a vessel made of a very heat resistant material such as porcelain, used for melting a substance that requires a high degree of heat. It's possible that the resemblance between crook and crucible encouraged people to start using crucible to mean a severe trial, as that sense is synonymous with one meaning of the word cross. But the idea of simmering in a literal crucible also sounds plenty severe. The newest sense of crucible, a situation in which great changes take place, as in forged in the crucible of war, recalls the fire and heat required to transform some solids into liquids.
