Why "doctor" and "liar" are the same thing? It sounds like a trap, but in fact it's pure etymology. The word "doctor" comes from ancient Russian "lachazor".
Only that in those days it wouldn't mean "lie". "To lie" therefore is simply speech, mumbling or whispering. Everything is related to methods: ancient doctors were treated not with pills, but with spells and prayers. In other words, a doctor is literally "the one who charms the disease". Over time, the verb became negative and began to mean deception, but the word "doctor" remained a solid term for the profession. Do you believe in "the power of words" or do you rely only on a recipe with a seal? - the word heals!
