Can’t Handle It
A successful effort is said to “pan out” because gold prospectors have long used a pan and water to wash out sand, dirt, and rocks when looking for gold ore, which sinks to the bottom of the pan and remains if the washing is done carefully.
The word “panic” comes from Pan, that horned and goat-legged Greek god. When not playing his Pan flute to nymphs in the forest, he commanded such a booming voice that his shout even terrified the giants during their mythical battle with the gods, causing them to “panic.”
The “Pan” in Peter Pan’s name is a reference to this goaty god.
Old flintlock muskets had small pans which held individual charges of gunpowder. A “flash in the pan” occurred when the gunpowder was ignited, but for whatever reason, no bullet was fired.
Pan also means “whole,” “all inclusive,” or “involving all members” in Greek, so it is a prefix that means all possible members of a group, such as in the words panacea (cure for all ills) pandemic (relating to everyone), pandemonium (all demons, or the uproar if they were all loosed), Pantheon (temple honoring all the gods), and Pan-American, for all people in the Americas, like the Pan-American athletic games.
Pan means bread in Spanish, so your local “panederia” is a bread shop or bakery, and “pane” is bread in Italian, so “Panera” means “bread time” in Italian, or breadbasket / breadbox in Spanish. “Panis” means bread in Latin, so many Latin-based languages have this prefix.
That room is called a “pantry” because bread was originally stored in there.
