Promulgating your esoteric cogitations or articulating your superficial sentimentalities and amicable, philosophical or psychological observations beware of platitudinous ponderosity. Let your conversational communications demonstrate a clarified conciseness, a compact comprehensibleness, and no coalescent conglomerations of precious garrulity, jejune bafflement and asinine affectations. Let your extemporaneous verbal evaporation and expatiations have lucidity, intelligibility and veracious vivacity without rodomontade or thespian bombast. Sedulously avoid all polysyllabic profundity pompous, propensity, psittaceous vacuity, ventriloquial verbosity and vaniloquent vapidity. Shun double- entendre, obnoxious jocosity and pestiferous profanity, observable or apparent.
