Background : I used to think that employing the word "right" to speak about good thinks was only an arabic culture trait - for instance the Quran describes good people with the expression "people of the right" in opposition with "the people of the left" who are the bad ones and when someone is seeing that something bode well or bring good omens we use "يتيمن" which means literally that "he goes right-handed with it",indeed the Arabic word for "right" is "يمين",a word that is also bound to the "south" cardinal direction.
Ironically,the word "omen" with its latin origins but undefined etymology sounds insanely - almost - the same as "يمين" !
When examining the french word "droit" , my intuition becomes just stronger : "droit" that means "right" and comes from the latin "directus"("in straight line") is the same word for "law","wright","jurisdiction","dexterous" and "erect".
When we go further,to say "left" in french we use these days "gauche" but the original word was "senestre" which bears a profound pejorative connotation (yes,it's the word for "sinister")...
It seems that English is not an exception ; "right" comes from the old word "riht" thus "good" while "left" comes from a whole family of pejorative vocabulary (weak,bad...)
Is there any other language (except those derived from Latin or semetic ones) that have the same trait ?
Is this the result of a psychological phenomenon or just a legacy from one very ancestral common language ?
