I’m not explaining this one to the kids. Someone else can.
Absolutely correct. Lady stems from bread-kneader, in fact: https://www.etymonline.com/word/lord
I’m going to go with Kevin Stroud of The History of the English Language Podcast on that one.
I can’t tell if you are implying any disagreement, so I’ll just add that the Proto-Germanic origin for the second half of lady (hlǽfdige) definitely stems from kneading: https://en.m.wiktionary.org/wiki/Reconstruction:Proto-Germanic/daigijǭ
Other than that, sounds like an interesting podcast!
