ABSTRACT
I use the comprehensive term 'particles' for adverbs, prepositions, and conjunctions, as these three "parts of speech" have so much in common that they are best treated together. A preposition may be called a transitive adverb having a noun or pronoun as its object; those conjunctions which serve to introduce a subordinate clause are adverbs (prepositions) having a clause as their objects; other so-called conjunctions (e.g. and) are simply particles used to join words or clauses.
