On ABZÛ we ripped out multiplayer and lots of other cruft from AActor and UPrimitiveComponent - dropping builtin overlap events, which are a kind of anti pattern anyway, not only saved RAM but cut a lot of ghost reads/writes.

Your presence inspired me to try to look up what the circumflex on "abzû" is supposed to signify. As best I can tell, it's a marker of vowel length.

I wonder how that came to be used. It's a traditional way to distinguish eta and omega in transliteration from Greek, but it's not at all a traditional way to mark long vowels in general.

(I see that wikipedia says this about Akkadian:

> Long vowels are transliterated with a macron (ā, ē, ī, ū) or a circumflex (â, ê, î, û), the latter being used for long vowels arising from the contraction of vowels in hiatus.

But it seems odd for an independent root to contain a contracted double vowel. And the page "Abzu" has the circumflex on the Sumerian transliteration too.)

"Abzu" is also the Greek onomatopoeia for a sneeze.

I was highly amused to learn that the ancient Greek verb for spitting is πτύω. (Compare English "ptooey".)

Yeah, and the modern is much the same ("φτύνω"). I'm sure it's onomatopoeic, and it's an amusing word.

Does the popular 'hawk' prefix for this also originate from ancient Greek ?

It's funny how I can sort-of read the Dutch word in "τύν": spit "tuf" and spitting "tuffen". I can't find the etymology of it so it might be a false cognate

If it isn't a false cognate, I wonder what the function of "φ" and "ω" are..

It is a false cognafe, it's not pronounced "oo", but "ee". It's just onomatopoeia, that's why it's so similar.

Seems to be an older convention in linguistics. Romanizations of Japanese also switched from circumflexes (Tôkyô) to macrons (Tōkyō) at some point in time fairly long ago—I think the English-language Japanese journal I saw using that convention systematically was from the late 1950s, and its recent issues definitely don’t use it.

Perhaps a circumflex was easier to typeset, like with logicians switching from Ā to ¬A and the Chomskyan school in linguistics switching from X-bar and X-double-bar to X' and XP?

We pronounce it t-uh-f, as in "tough" without the o.

Mandarin is 吐 /tʰu/.

Note that ν is an N, not a V. I think the standard transliteration of φτύνω from modern Greek would be "ftino".

(Note also that "tough" is pronounced t-uh-f /tʌf/, with nothing O-like anywhere in it.)

I wonder if that's because of the two different ways you can spit: without windup ("tuf" sound) and with windup / breathing in ("hff-tuf" sound).
