New Word: “Piscene”

I knew that “piscis” was a astrological sign, but it didn’t occur to me that the word was simply Latin for “fish” and would be the root of other words.

Of or relating to fishes. Having the appearance or characteristics of a fish.

From a passage where the author expresses “piscine ignorance” of how fishes breathe underwater.

(My Chrome browser spellcheck, for the record, has flagged the word as misspelled with the squiggly red underline.)
