I did a beginner's search through WR.com and I found only hundreds of salutations. If there is no other thread on that, does anybody know something about the origins of Hello, other than what I find in Etymoline? The motivation behind my question is the similarity with the Homeric greeting "Oule" (ούλε) (Od. 24, 402, http://www.theoi.com/Text/HomerOdyssey24.html ). This is the imperative of the v. oulo (I'm in good health) http://www.perseus.tufts.edu/hopper...habetic+letter=*o:entry+group=80:entry=ou)/lw. Thanks.
