Question: One of Joonas's old Qs. has made a welcome return: [Is there a Latin euphemism for going to the toilet?](https://latin.stackexchange.com/q/516/1982). This brought to mind the fatuous things we say about death: "He's passed over."; "He's passed on."; currently in vogue; "He's passed."; this could be, "He's (the) past." reflecting American gangster-vernacular, "He's history.".

Much of this is driven by embarrassment (and fear of death), especially when talking to the bereaved--what do you say?

I'm just as bad, using Cockney (London) rhyming-slang, "He's brown-bread.".

Did the Romans use euphemisms for "death" & "dying"?

Answer: 
I believe acquiescere, excedere, and decedere were used euphemistically. excedere and decedere could be used with "de vita". Lewis and Short also lists "vixit"(he lived) as a euphemism for having died, as well as euphemisms like "si quid factum sit aliquo", "if anything happens to anyone" aka "if anyone dies". I'll try to come up with some more information, but I hope this satiates your curiosity until then.
A method that often deliver nicely is searching the fully digitalized L&S dictionary, but *from* the English. [Searching "to die"](https://www.google.com/search?q=%22to%20die%22%20%22Charlton%20T.%20Lewis,%20Charles%20Short,%20A%20Latin%20Dictionary%22%20site:http://www.perseus.tufts.edu/hopper/text%3Fdoc%3DPerseus:text:1999.04.0059:&ei=C_7qYMeEDImH9u8P3tKu4Ag&start=0&sa=N&ved=2ahUKEwiHtpmXm9vxAhWJg_0HHV6pC4w4MhDy0wN6BAgBEDU&biw=1920&bih=973) for example does indeed bring up some nice results, the majority of which I won't include here for they are either already mentioned in other answers or not euphemisms in my opinion; Nevertheless, I do encourage the reader to take a look.

**Naturae satisfacere**:

> 
> de eo qui et **naturae** et legibus **satis fecit** (Cic. Clu. 10, 29).

Along with this L&S [mentions](http://www.perseus.tufts.edu/hopper/text?doc=Perseus:text:1999.04.0059:entry=natura) ***naturae concedere***.

Another nice expression that comes up is **naturae debitum persolvere/solvere/reddere**, literally to pay the debt to nature:

> 
> morbo naturae debitum reddiderunt (Nep.Vit.Reg.1.5.2)
