Salient is an adjective that means most noticeable or important.
The most common use of salient is to describe something that stands out or is most obviously noted. But it may also be used to describe an animal standing on its hind legs as if leaping. This explains why our word of the day comes from the Latin Salire (say LEER ay) meaning to leap.
Jeff’s observation about the house’s strange smell was pretty salient. That odd odor was the first thing that stood out when we entered it.
