E-Prime (short for English-Prime) is a modified form of the English language which eliminates all forms of the verb to be: “be”, “is”, “am”, “are”, “was”, “were”, “been” and “being” (and their contractions ‘m, ‘s, and ‘re). Sentences composed in E-Prime seldom contain the passive voice, which in turn may force writers or speakers to envisage things differently than they might otherwise. By eliminating most uses of the passive voice, E-Prime encourages writers and speakers to make explicit the agent of a statement, possibly making the written text easier to read and understand.
Some people use E-Prime as a mental discipline to filter speech and translate the speech of others. For example, the sentence “the movie was good”, translated into E-Prime, could become “I liked the movie”. The translation communicates subjective experience rather than judgment. In this example, using E-Prime makes it harder for the writer or reader to confuse a statement of opinion with a statement of fact.
