Reason?

Fragment of a discussion from User talk:Rua

Is that your opinion or do you have any sources, or are taxonomical terms always nouns? And what's the POS of marmorata in "Felis marmorata" or "vibrans" in "Seioptera vibrans"? I guess, we can already agree that Felis is a feminine noun. -84.161.45.96 01:56, 13 February 2017 (UTC)

PS: This was an answer to CodeCat's first reply. And it's partly a rhetoric question, because ICZN 11.9 is clear: "A species-group name must be a word of two or more letters, or a compound word (see Article 11.9.5), and, if a Latin or latinized word must be, or be treated as, [...] an adjective or participle in the nominative singular (as in Echinus esculentus, Felis marmorata, Seioptera vibrans) [...]".
@CodeCat: ICZN talks of POS like nouns, adjectives and participles. Also noun (that's what you readded into sapiens) is a POS too. If POS would not make sense for taxonomical terms, then it would have to be ===Word===. -84.161.45.96 02:01, 13 February 2017 (UTC)
