This word is particularly apt for this blog. According to Thomas Blount's Glossographia in 1656, it means the expression of a word, the etymology of a word. This is exactly what this blog is all about, discovering the meanings of words, their origins and and earliest recorded usage.
Veriloquy also means truth speaking, from the Latin veri meaning truth, and Latin loquis meaning to speak. This word has been used since the 17th century. Other words with similar origins are veriloquent, verity and verily.
