etymology jokes on Lemmy.... ive Waited for this day for so long

nah there's no "wrong" for a common native pronunciation. but for silent p- words specifically, the /pt/ and /ps/ consonant clusters just don't occur at the start of words in English. so the p goes silent in those words. pterodactyl, psychology. but in languages like Greek and German they do occur!

Depends on whether the o is before the p or after the r.
