When taken in a certain context laconic and pellucid are word opposites
According to Wikipedia the “laconic” phrase refers to “specially a blunt and elliptical rejoinder…named after Laconia, the region of Greece including the city of Sparta, whose ancient inhabitants had a reputation for verbal austerity and were famous for their blunt and often pithy remarks.”
Moreover, the meaning of blunt refers to ”Having a thick edge or point; not sharp quotations…dull in understanding; slow of discernment; opposed to acute Quotations…abrupt in address; plain; unceremonious; wanting the forms of civility; rough in manners or speech. Quotations…”
The elliptical rejoinder of laconic “refers to the omission, from a clause, of one or more words that are nevertheless understood in the context of the remaining elements..."
Furthermore, if you are laconic, then you say what you are thinking in just a few words that can be "at times considered as dull and insensitive..."
For instance, POTUS 45 is the “laconic” master of what was until recently 140 characters Twitter, because he Tweets sparingly either about the latest controversy or sets out a new laconic view of critics—he also fuels the latest media frenzy about those blunt and elliptical words, then laconic POTUS 45 fuels the next Twitter storm lashing out at the media who have no inclination to decipher POTUS 45’s previous ”laconic” Tweet.
The "pellucid" word is the standard for political talking points, and the pellucid sentence is theme oriented with easy to understand pellucid words.
For example, those politicians who want to become the major media’s favorite politician, must be adept at speaking in specific pellucid phrases composed of pellucid themed talking points aimed at defeating the opposition’s agenda, and major media’s favorite political personalities always use simple phrases that cannot be misunderstood, this is especially important for players of prominence in the political arena, like John McCain, who is a master of the politic pellucid barb.
As another example, the Democratic spokespersons, Nancy Pelosi and Elizabeth Warren are extremely adept at formulating pellucid phrases like “a nation of sick people who can’t afford health care” or “the tax plan for the rich”—these pellucid word phrases are simple easy to understand and cannot be misunderstood, perfectly aimed to penetrate through the public’s perception about the Republican agenda.
While the pellucid Maxine Waters' aim is to cause turmoil, the words “impeach 45” are formulated with a pellucid theme: impeach.
A word of advice, don’t plan on a political career if you are a "laconic" speaker who uses laconic themed phrases, but if you are a talented composer of the "pellucid" theme, politics could be your eventual direction.
