How to use "keep at bay"

What Does "keep at bay" Mean?

• Idiomatic meaning: To prevent someone or something from approaching, attacking, or having a harmful effect. It implies maintaining a distance from a threat that is persistent or looming.
• Origin: The phrase originates from medieval hunting. When a quarry (like a stag or boar) was cornered by hounds and forced to turn and face them, it was said to be "at bay." The hunter would then "keep the animal at bay" using a weapon to prevent it from attacking while waiting for the rest of the party.
• Register: Neutral to Formal. It is equally at home in high-quality journalism, academic writing, and professional settings.

How to Use It

• Grammatical flexibility: The phrase is highly flexible. You can "keep [something] at bay" or "hold [something] at bay." It can be used in the passive voice ("the virus was kept at bay") and is frequently modified by adjectives like "just enough" or "successfully."
• What sounds unnatural: Using it for positive things (e.g., "keep my happiness at bay") is incorrect, as the idiom specifically refers to warding off threats, unpleasant emotions, or physical dangers. Using literal water-based imagery (like a maritime bay) usually results in a confusing pun rather than the intended idiom.
