How to use "keep something at bay"

What Does "keep something at bay" Mean?

• Idiomatic meaning: To "keep something at bay" means to prevent someone or something—usually something unpleasant, dangerous, or threatening—from approaching you or having a harmful effect. It implies maintaining a distance from a problem rather than necessarily solving it permanently.
• Origin: The phrase originates from medieval hunting. When a quarry (like a stag) was cornered by hounds and forced to turn and face them, it was said to be "at bay." The hounds were kept "at bay" by the animal's horns or position, unable to close in for the kill.
• Register: This expression is neutral to formal. It is equally at home in high-level journalism, scientific writing, and everyday professional conversation.

How to Use It

• Grammatical flexibility: The phrase is highly flexible. It can be used in questions ("How do I keep it at bay?"), negated ("They couldn't keep the tide at bay"), and the "something" can be a physical object (weeds, pests) or an abstract concept (fear, reality).
• What sounds unnatural: Using it for positive things sounds odd (e.g., "I kept my happiness at bay"). It also sounds unnatural when used for things that aren't actually threatening or encroaching. Avoid over-modifying the phrase; saying "keep it at a very far bay" is non-standard and breaks the idiom.
