Etymology: "Supinations" is the plural of "supination," which names the outward turning of the palm so that it faces upward, as when you hold out your hand to receive something. The noun is built from "supine" plus the suffix "-ation." "Supine" comes from Latin "supinus," meaning lying on the back or face-up, and its sense of turning the palm upward carries that same face-up idea. The suffix traces back through Old French "-ation" to Latin "-ātiō," a common ending for forming nouns of action from verbs and adjectives. The plural form simply counts separate turns of the palm, so a physiotherapist describing a sequence of wrist movements might speak of several supinations in a row. Its opposite, pronation, turns the palm downward.
