Recently on a linguistics Discord server, I asked the smart people about how the word “voxblade” sounds:

One setting element of the game is a lexemantic tool currently called a *voxblade* which stores, amplifies, and shapes the voice of the were-angel wielding it into a standing soundwave-edged blade. The blade glows faintly by the physics phenomenon of sonoluminescence and evinces the individual characteristics of its wielder.

Question: *voxblade* has four consonant-y sounds in a row: K, S, B, L which doesn’t quite roll off the tongue. Is there anything in linguistics that’d guide me to some sort of more euphonic name for this thematically rich tool? Aside from brute force checking a bunch of possible word combinations? Like, I can script up quantitative linguistic guesswork like that, but is there some covering law of esthetic “ear-feel” or euphony?

Vaguely I have some limited conlanging sense of how Tolkien made elvish sound different and more pleasing than some of the other languages he developed. But how did he do that?

Disclaimer, I’ve not studied linguistics formally but I am having an absolute blast learning from this podcast and Anne Curzan’s Wondrium lecture series *Secret Life of Words*, as a total amateur. I will chase down and learn about anything you care to point me in the direction of.

…and the responses were surprisingly positive! They pointed out that common words like “explode” has the same phonemic sequence, and nobody seems to mind it. 
So, pressing on with voxblade!

Now that I think about it, it sounds good to me to run “vox” together with the following specific tool or equipment unless the tool name has a stop sound. So:

Voxblade

Voxhammer

Voxshield

but

Vox Tonfa
