lol, you are contradicting yourself, first you point out there is a connection, and decry it as being "folk" or "not real" or, dare i say it "naive" yes, naive is based on the english word "knave" which means fool

but you are engaging in fallacy because you are claiming superior knowledge when the reality (oh, that word) is that people use words as they understand them, not as the high council of words decrees.

as for "ortho" and "straight" and "upright" being related, again these are just as folk related as anything else i just said... and the arabic word for "straight" is "serrata" (it's part of the salah, idinha serrata means "straight path" or "path straight" to respect the order)

there is no such thing as an "orthodox" intepretation of language, this is a fallacy as well

humans have imaginations and are stupid (knaves) and the most outstanding naievete is that of the so called expert, and what is more toxic is "expertism" is a thing that is touted often by "councils" (which is a perversion of counsel, which means to advise) as the right decision as justification for what is in fact the profit of the council members and the detriment of those who are stupid enough to obey this council (soviet, savet, junta, communa)

just because the link may be weak or not obvious doesn't mean it isn't part of the social matrix, it almost always is, and that's why the sounds and consonants, especially, tend to relate
