"discord" means disagreement. There is an application, named "Discord", for online conversation. Does discord have another meaning which is probably more suited for the application, or is the application intended for disagreement? Isn't "Discourse" more suitable for the application?
Just wanted to add an explanation from Discord, from an AMA where they explain the name:
We picked the name because at the end of the day it just sounds cool and has to do with talking.... And Discord in the gaming community is the problem we are trying to solve with this product.
The word "discord" only has negative meanings roughly meaning disagreement, bad vibes, or actual fighting due to disagreement or bad vibes. It's a very strange name for a communication app and it took me a while to get used to it.
So yes, "Discourse" would have been a more descriptive, less jarring name.
Discord, accord, and concord all have a similar "cord" root.
Etymologically, it's related to the root word for "heart". In this use though, it's more like speech from the heart: accord is general acceptance without the need for speech; concord is speech that all aligns and agrees; discord is conflicting and chaotic speech.
The presence of discord almost inevitably means some major underlying disagreement, and 99% of use means just that. But, similar to the word "pandemonium," it's not strictly negative.
