PREPOSITIONS AND CONJUNCTIONS.
§ 390. _Prepositions._--Prepositions are wholly unsusceptible of
inflection.
§ 391. _Conjunctions._--Conjunctions, like prepositions, are wholly
unsusceptible of inflection.
§ 392. _Yes_, _no_.--Although _not_ may be considered to be an adverb,
_nor_ a conjunction, and _none_ a noun, these two words, the direct
categorical affirmative, and the direct categorical negative, are referable
to none of the current parts of speech. Accurate grammar places them in a
class by themselves.
§ 393. _Particles._--The word particle is a collective term for all those
parts of speech that are _naturally_ unsusceptible of inflection;
comprising, 1, interjections; 2, direct categorical affirmatives; 3, direct
categorical negatives; 4, absolute conjunctions; 5, absolute prepositions;
6, adverbs unsusceptible of degrees of comparison; 7, inseparable prefixes.
