salient

The heraldic sense “leaping” and the sense “projecting outward” are borrowed from Latin salientem, the accusative form of saliēns (“springing, leaping”), present participle of saliō (“leap, spring”, verb). The senses “prominent” and “pertinent” are relatively recent, and derive from the phrase salient point, which is a calque of the Latin punctum saliēns, a translation of Aristotle's term for the embryonal heart visible in (opened) eggs, which he thought seemed to move already. Compare also the German calque der springende Punkt.
