Etymology

Origin of supine

First recorded in 1490–1500, supine is from the Latin word supīnus lying face up, inactive

---

Explanation

You can be described as supine when you're lying face up — for example, your favorite yoga poses might be the supine ones. Someone who is very passive or lethargic could also be called supine — for instance, someone might be supine in the face of continuous threats and insults. The adjective supine comes from a Latin word, supinus, which means “thrown backwards” or “inactive.” Whenever a person or animal is lying on its back, belly-up, it is supine. When your hand is open, palm-up, it is also supine. Supine can even describe a person who gives insufficient resistance, or who is lazy and ineffectual. "When Jack refused to object to the landlord’s repeated — and gouging — rent increases, he was supine."
