They name the city Vanda Nossëo. Findekáno's family arrives to speak with them a week later, but they mostly seem to want to speak to Findekáno, and he leaves with them for a while and then placidly comes back. No one comments. Fëanor quizzes her about harmonics and runs the tests of plain speech that he wanted.
She is happy to answer questions about harmonics and indulgent about tests of plain speech.
She can't even speculate why there'd be an exception for animals, that's weird. They're probably just piggybacking on the special snap-into-place nature of person names somehow.
Not exactly, but she can tell they mean similar things, except the last one, which is specific. She is not at all sure which exactly of these concentric groups is the gradation at which one encounters weirdness about pet rocks.
...she'll repeat the word a few times under various conditions. No, group names like that do not constitute names in the clicky sense, only a person's first, real name.
She's pretty sure names for groups do not tend to count unless they are also names for the members of the group in the clicky sense. She could probably call him and his sons Finwëans and have that preserved as a name.
...she is probably missing something as a member of a nonreproductive species but that seems a little bizarre to her.
"...There's not really anything I can think of. Many very bad fairies still abide by chosen nicknames but I don't think it's universal."
