theobromide
Oh I'm aware of it. I just know it's not relevant for Wiktionary, because Wiktionary considers languages regardless of standards. The only standard Wiktionary follows is "real life". That is, it follows what people actually say and use, and what usage we can find evidence for "in the wild", and not what people tell others to use. For example, if there were a durably archived source in which the sentence "There is some theobromide in my coffee" were used, then that would count as valid evidence for inclusion for Wiktionary's purposes. But any source that actually tells people that "theobromide" is not a valid word is not. To say it another way, Wiktionary describes usage, but it does not prescribe/proscribe nor does it regard any prescriptive authority as authoritative.
Maybe you should see WT:CFI. If you are familiar with Wikipedia, then WT:WFW might also be useful.
