Sources and evidence
Sources are shown with the role they play in this guide. Historical or style-sensitive claims are kept within the evidence boundary described above.
“Come rain or shine” expresses commitment or certainty despite changing conditions. It can refer literally to weather, but its ordinary idiomatic use is broader: something will happen regardless of difficulties or circumstances.
“Cross that bridge when we come to it” means deal with a possible problem if and when it actually arises instead of worrying about it in advance. An 1851 Longfellow text directly preserves an older negative form and explicitly calls it an old proverb.
“In hot water” means being in a difficult situation in which you are likely to be punished. The guide gives the current meaning without attaching an unsupported exact origin date.
“Between a rock and a hard place” describes being trapped in a very difficult situation that requires a hard choice. This guide publishes the current meaning supported by Cambridge and does not add an unsupported exact-origin chronology.
A “can of worms” is a complicated situation that produces many further problems when you begin to deal with it. Cambridge marks the idiom informal. Use it for a problem that opens into further complications, not merely for a single isolated difficulty.
A “Catch-22” describes an impossible situation in which one requirement depends on another condition that cannot be met first. Use it for a self-defeating dependency or circular trap, not merely for any difficult choice or ordinary dilemma.
Double bind describes a trap created by incompatible expectations or choices. In ordinary writing it can describe a practical dilemma; specialist psychological uses can carry narrower theoretical meanings.
“Face the music” means accept criticism, punishment, or responsibility for something you have done. The guide gives the current meaning without attaching an unsupported exact origin date.
