Definition of Coordinate Conjunctions

Definition: A type of conjunction that is used to connect two words or groups of words of equal grammatical status. The most common coordinating conjunctions are "and" and "or" in English, y and o in Spanish. "But" (pero) is also sometimes used as a coordinating conjunction.
Some words are satisfied spending an evening at home, alone, eating ice-cream right out of the box, watching Seinfeld re-runs on TV, or reading a good book. Others aren't happy unless they're out on the town, mixing it up with other words; they're joiners and they just can't help themselves. A conjunction is a joiner, a word that connects (conjoins) parts of a sentence.
Among the coordinating conjunctions, the most common, of course, are and, but, and or. It might be helpful to explore the uses of these three little words. The examples below by no means exhaust the possible meanings of these conjunctions.
