CONJUNCTION, a general term signifying the act or state of being joined together. It is used technically in astronomy and grammar. In astronomy, two bodies are said to be in conjunction in right ascension or longitude when they have the same right ascension or longitude. The conjunction of Mercury or Venus with the sun is "superior" when the planet lies beyond the sun, and "inferior" when the planet is between us and the sun. In grammar the term "conjunction" is applied to one of the so called "parts of speech," viz., those words which are used to "join together" words, clauses or sentences. Conjunctions are variously classified according to their specific function; e.g., adversative ("but," "though") which contrast, illative ("there where the second sentence or clause is an inference from the first, temporal where a time-relation is expressed, and so forth.
