I cannot seem to find anything on this. I see (in dictionaries, although not all of them) that the first syllable is stressed (I've been corrected countless number of times on this, too).
That means that many believe that saying it with stress on the second syllable is a way to broadcast that "you're an uneducated dummy who doesn't know how to pronounce it." But why? I don't understand.
The word "participate," for example, is on the second syllable, and it appears to me that the words are related etymologically (somehow...).
According to: https://www.etymonline.com/word/participle
participle in the grammatical sense (13c.), a variant of participe, and directly from Latin participium, literally "a sharing, partaking,"
This means that participe and participium are BOTH first-syllable pronunciations? That doesn't make sense.
Can someone explain? Or find some information that the second syllable is truly the wrong way to pronounce it?
