On the etymology of "folk", saying that it the word comes from Old English folc is true, although a vast over-simplification. A lot of languages share this word.

This is actually an ancient word, you can trace it back to proto-Germanic "fulka", and further to Proto-Indo-European "plh-gos" (presumably pronounced something like phulgos or pholgos, close enough to folk).

If you want its direct ancestor, then it's perfectly true. The etymology further back than that would be irrelevant, and also unattested.

OA here. Thanks for the expanded etymology. I was using https://www.etymonline.com/word/folk as my source which goes into more historical detail. But didn't want to get too carried away in the opener on etymology.

Folksy: people doing good or neutral stuff

Vulgar, populist: people doing naughty or debased stuff

...and then from phulgos to the latin "vulgus"?

Where "vulgate" and "vulgar" come from, the common.
