Hello again doron. There's a little note in
Tolkien's
Words, Phrases and Passages (published in
Parma Eldalamberon 17) revealing that
Quenya namárie "be well" is a formula for greeting or farewell.
🐾
In south German (I believe Bavarian, specifically), there is the term "servus" (some kind of corrupted Latin, I would guess) that can also be used both for greeting or farewell.
I have a private hypothesis about the reason for this Bavarian specialty (though my knowledge of other German dialects, and we have a lot of them, is very spotty). Bavaria is well-known for (one sort of) beer festivals, the best-known world-wide certainly being the Oktoberfest in Munich. We have one of the regionally best-known ones besides the Oktoberfest, in the
city I live in, and with which I'm far more familiar with than the Munich one (and as for that, ours, originating in 1755, is 55 years older than that poor copy in Munich, starting in 1810 😝 ).
If one sits around gabbing and babbling away with a bunch of friends long enough, the 1-liter steins being replenished at regular intervals, it may become somewhat unclear if someone one is addressing just arrived or is just leaving; and the term itself is spoken with very little lip movement, never mind complicated ones. Perfect thing for a situation with declining verbal skills … 🥴
