discernible

adj

Etymology: From Middle French discernable; spelling changed from -a- to -i- in the 17th century to conform to Latin discernibilis. By surface analysis, discern + -ible.

1. Possible to discern; detectable or derivable by use of the senses or the intellect.

   “There is a discernible performance difference between a Porsche and a Civic.”

   “To have demolished and rebuilt the walls, would have been a very costly expedient, and as the least of two evils, the painter's brush was resorted to; here and there however, above some of the windows, the black wreathings of the smoke are still discernible through the white covering.”
