widely known and that may have all manner of uncommon or special features, it
may help a lot to introduce new special terms (or use old terms with specially

However, jargon also is often used to given oneself airs, to obscure or
obfuscate, or just carelessly, and anyway has the property that when it is not
addressed to the specialists for whose ends it exists that it makes for
unnecessarily difficult prose.
In short: Jargon should be avoided, except in circles where it really
belongs to the terms of the trade. Speak plainly, or don't speak at all!

may fondly imagine that a few gifted persons may have some use for the
Philosophical Dictionary that
contains this lemma.
