Definition

Idiom (Verb phrase): - To be in a very dangerous or uncertain situation; to depend on a very small or fragile thing: This idiom describes a state where something (like a situation, a plan, or a life) is at great risk of failing or ending. Its outcome depends precariously on a single, often minor, factor.

Usage

This idiom is used to emphasize extreme vulnerability or imminent danger. It is often used in passive constructions (e.g., "hangs by a thread," "was hanging by a thread"). - It typically describes critical situations such as survival, success, or stability. - The "thread" metaphorically represents the last, thin hope or condition preventing disaster.

Examples
