róma

noun. horn, [ᴹQ.] loud sound, trumpet-sound, *blare; [Q.] horn

A word glossed “horn” in the Quendi and Eldar essay of 1959-60 in phrases like Q. róma Oroméva “Orome’s horn” (WJ/368), clearly a reference to Q. Valaróma (S/29). In The Etymologies of the 1930s, however, ᴹQ. róma was glossed “loud sound, trumpet-sound” under the root ᴹ√ROM “loud noise, horn blast” (Ety/ROM). In The Etymologies the word for “horn” was ᴹQ. romba, a word that also appeared as Q. romba “horn, trumpet” later in the Quendi and Eldar essay (WJ/400).

Neo-Quenya: For purposes of Neo-Quenya I would use róma mainly for horn blasts and trumpet sounds. I would only use it for “horn” metaphorically in words like Valaróma, and for the ordinary word for “horn” I would use romba.

Conceptual Development: The Qenya Lexicon of the 1910s had ᴱQ. likinne and [lik]inde “blowing of horns”, both elaborations of ᴱQ. likin “(curled) horn” (QL/54).
