a quick trawl of my lexicon for ullalk brought up a single word with [mw], [lúmw] - 'rank' and a single word with [lw], [skólw] - 'haft'. A google search turned up nothing, so I'm not sure how common or stable something like this is

oops, yes, múlːək is correct originally being muːlokas in the proto language, but nɛlfəs should be nɛlf! Not sure how that slipped past my sound change applier.

To call someone "Kossam" /kósːəm/ 'marked' lit. 'struck repeatedly' is to liken them to that of the most depraved criminals, devils, and demons. Not only graceless, but having been marked by a god as a deceiver or a vile person.

The name of the God of death is so taboo that the euphemism Sanas Falk /sánəs fálk/, lit. Mourning Beast, has entirely supplanted it and the original name has been lost to time.

Similarly, the name of the God of fire has become synonymous with "sinning" (3/4)

As for religious ones, the names of deities not worshiped by the Nimmen are often used alongside general terms for gracelessness, or to not be in the favor of any god, which is almost considered more blasphemous than worshiping the wrong god. (2/4)
