How it's used

This expression vividly describes a physical reaction to intense fear or anxiety where one loses the strength to stand properly. It is often used in hyperbolic ways to describe situations that are not life threatening but are nonetheless startling or intimidating. The imagery of 軟蹄 refers to the legs becoming soft or jelly like, effectively capturing the loss of motor control under stress.

Examples

I really went weak at the knees with fear when I saw that big cockroach.
Did you go weak at the knees with fear when you walked on that suspension bridge?

Common phrases

scared until weak at the knees

Common mistake

Do not use this to describe physical exhaustion or muscle fatigue from exercise, as it specifically implies a reaction to fear or shock.
