Here we have 54 words referring to manners or styles of speaking, words that use the suffix '-loquent', '-loquence', or '-loquy', from Latin loqui (to speak). While in an age of text-messaging, public speaking has lost its once-vaunted status as a communication medium, as long as people meet face to face, others will judge them on their manner of speech. As a university instructor, I know only too well the perils of many of these words. One of my (friendly) rival word lists online and a favourite site of mine is the Grandiloquent Dictionary. Curiously, many '-loquence'-suffixed words are lost words, and thus cannot be included here.
