How it's used

Originally referring to the practice of keeping a guard dog or a small amount of cash at home for sudden emergencies, this phrase now almost exclusively relates to stocking up on household essentials like medicine, non-perishable food, or basic tools. It carries a sense of prudence and foresight, suggesting that one is preparing for a rainy day rather than just hoarding items. You will frequently hear it used to justify why someone has bought more than they currently need.

Examples

It is better to keep some medicine at home for emergencies.
Are you buying so many canned goods to keep on hand for emergencies?

Common phrases

buy in advance for emergencies
medicine for emergency use

Common mistake

Do not confuse this with literally watching a door or guarding an entrance. While the literal meaning of the characters suggests guarding a gate, the idiomatic usage is strictly about preparation for future contingencies.
