Secondly it is well known by linguists and experts who even study Harari and Ethio-semetic languages that , ''Garaad'' and even ''Aw'' (Father) and ''Ay ''(Mother) are loan's from a cushitic source because there is no etymological links and nor does it have a Harari-Ethio-semetic root.
This is from the
Vocabulary analysis of the Harari language by Wolf Leslau
He made the list but didn't locate which cushitic language is the definite source because of lack of lexical comparison from those languages at his disposal but i like that he is more honest than some of these writers who run of with assumptions, that turn out to be false,
Besides the word ''Garaad'' and ''Aw'', i can pick out a couple of loan words from the list that i think are Somali in origin like:
Dumaal, Bun(Coffee), Ay(Mother), Fula (coward), ilaalo/ilaalo(Watch tower), MaxMaxa(Proverbs), Dirre(Plain), Tumtu(ironsmith) , Garab( Side,direction), Waraba(hyena), Gessi (Brave), Danta(Care for something), Daran(surpassing limit), Bilis(who is not a slave), Bon(tanner) , sor/sur (food offered to a group of people on special occasion/ porridge) etc.
