I am firmly convinced that the customary mapping of widow/orphan is back to front. You’re really trying to convince me that the one that has been cut off from its antecedents is the widow? It should obviously be the orphan.

So, no wonder people confuse them, because the popular mapping is wrong.

Yes! All the typographical techniques and terminology is fascinating (and confusing at times). Widow and orphan control really fight against text justification. Finding the right balance is tricky, but LaTeX has all the little knobs to tweak and find what's right for your uses (fiction for me).
