Dictionary.com entry for Altiloquence
Lofty speech; pompous language.
Not finding an exact entry for the origin of altiloquence,
I think it is completely of Latin origin because of
the two following entries which relate to today's word:
Online Etymology Dictionary entry for altitude c.1391, from L. altitudo (gen. altitudinis), from altus "high"
phrontistery.info page listing words about manners of speech referring to manners or styles of speaking,
words that use the suffix '-loquent', '-loquence', or '-loquy', from Latin loqui (to speak)
Have you ever had your enthusiasm and longstanding familiarity
with a topic mistaken for mere altiloquence? Me neither!
