10.1 Conjunctions in Greek work much as they do in English. Greek, however, uses them far more often, and frequently in more subtle ways, than formal written English does. This is in part because Greek has a strong tendency to link clauses and sentences together. While consecutive sentences in English are most often separated by a pause (period), many consecutive sentences in Greek are instead marked or offset by coordinating conjunctions, such as and, but, and therefore (S 2163).
