IPA: /dɪˈsɜːrnəbl/

Able to be seen or noticed; something that can be recognized or distinguished.

Discernible → It is formed from "dis-" (meaning apart) and "cernere" (meaning to separate or distinguish). The word "discernible" means capable of being distinguished or recognized as separate from others.
Think of being able to 'separate' ('cernere') things that are 'apart' ('dis-') — that's why discernible means something that can be recognized or distinguished.
