<P> In grammar, a conjunction (abbreviated CONJ or CNJ) is a part of speech that connects words, phrases, or clauses that are called the conjuncts of the conjoining construction . The term discourse marker is mostly used for conjunctions joining sentences . This definition may overlap with that of other parts of speech, so what constitutes a "conjunction" must be defined for each language . In English a given word may have several senses, being either a preposition or a conjunction depending on the syntax of the sentence (for example, "after" being a preposition in "he left after the fight" versus it being a conjunction in "he left after they fought"). In general, a conjunction is an invariable (non inflected) grammatical particle and it may or may not stand between the items conjoined . </P> <P> The definition may also be extended to idiomatic phrases that behave as a unit with the same function, e.g. "as well as", "provided that". </P>
