To have something in reserve
Meaning
To keep a supply of something available for future use or unexpected needs.
Origin
The phrase "to have something in reserve" draws its strength from the ancient and deeply practical concept of foresight. The word "reserve" itself originates from the Old French "réserver," stemming from the Latin "reservare," meaning "to keep back" or "to save." This fundamental idea of setting resources aside isn't tied to a single moment but reflects a primal human need—from ancient civilizations storing grain for lean winters to medieval armies keeping fresh troops ready for battle. The military application, in particular, solidified the phrase's meaning, where "reserve forces" or "ammunition in reserve" were critical for survival and victory. It's a testament to planning and prudence, a recognition that immediate needs aren't the only ones, and that a hidden supply can make all the difference when the unexpected strikes.
Examples
