If something stands out in a very obvious way, it can be called salient. It's time to find new friends if the differences between you and your current friends are becoming more and more salient.
Salient, from the Latin verb salire "to leap," was originally used in English to refer to leaping animals such as a frog or deer and may still be used this way. Often, however, it is used in math or geography to mean protruding. A salient angle juts outward rather than inward. Figuratively, it means noticeable or prominent. When giving an argument, make your most salient points at the beginning or the end.
