Why “suaviloquence” is a great word
SUAVILOQUENCE — [Noun] The quality of being pleasingly smooth, agreeable, or sweet in speech or writing. From Latin suāviloquentia, from suāvis ("sweet, pleasant") and loquentia ("speaking"). First attested in English a1649. Unlike eloquence, which emphasizes persuasive force, or bluntness, which denotes jarring directness, suaviloquence is the deliberate confection of a charming tone. It is the diplomat’s calibrated ambiguity, the honeyed prose of a bygone love letter, and the flawlessly courteous reply that perfectly masks a refusal—the gentle artifice that makes the message slip down without a trace of grit.

- The quality of pleasantness or sweetness in speech or writing.“When a professional man is called from his office, or a student from his books, deliver your message with all possible despatch. Have not the vanity to think that great novelty of thought, even though you can deliver it with great suaviloquence, will be gladly received by those whose minds are pre-occupied.”
