[§ 443]. Conjunctions.—Conjunctions, like prepositions, are wholly unsusceptible of inflection. Like prepositions they
are never made by means of a derivational element. Like prepositions they are either simple (as and, if), or complex (as also, nevertheless).
The conjunctions of deflection originate chiefly in imperative moods (as all save one, all except one); participles used like the ablative absolute in Latin (as all saving one, all excepting one); adverbs (as so); prepositions (as for); and relative neuters (as that).
The absolute conjunctions in the English language are and, or, but, if.
[§ 444]. Yes, no.—Although not may be reduced to an adverb, nor to a conjunction, and none to a noun, these two words (the direct affirmative, and the direct negative) are referable to none of the current parts of speech. Accurate grammar places them in a class by themselves.
[§ 445]. 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 affirmatives; 3, direct negatives; 4, absolute conjunctions; 5, absolute prepositions; 6, adverbs unsusceptible of degrees of comparison; 7, inseparable prefixes.
