The Wonders of Etymology on Right and Left

Etymology(the study of words),along with English, makes language fascinating.

Take the words "left " and "right”. People can conclude that one is derogatory than the other. The word 'left' in many languages is associated with evil or the devil. However, the Greek "dexter" gives us the word "dextrous" (skilful) means "on the right". ‘Left' (from Old English lyft) means 'weak, worthless’. Among the Nyoro in Africa, for example, 'left' means 'hated', and in Japan it means 'crazy'.

Common words which we people speak nowadays also regard left a defamatory concept than its counterpart. Did you ever hear the words lefteous, or even upleft in conversations, perhaps?
