On one's last legs

Origin

Imagine a weary traveler, stumbling along a dusty road, their legs trembling with exhaustion after countless miles. Or perhaps an ancient, rickety chair, its joints groaning, threatening to give way with the slightest weight. This vivid, physical image of imminent collapse is the heart of "on one's last legs." The phrase, surfacing in English in the late 18th century, paints a picture of something—be it a person, an animal, or even a once-grand institution—that is so utterly spent, so worn down by time or trial, that its very foundations are failing. It's the moment before the fall, the final struggle against inevitable decline, capturing the universal plight of exhaustion and decay with stark, relatable honesty.
