E-Prime (short for English-Prime or English Prime, sometimes É or E′) denotes a restricted form of English in which authors avoid all forms of the verb to be.
E-Prime excludes forms such as be, being, been, present tense forms (am, is, are), past tense forms (was, were) along with their negative contractions (isn't, aren't, wasn't, weren't), and nonstandard contractions such as ain't and 'twas. E-Prime also excludes contractions such as I'm, we're, you're, he's, she's, it's, they're, there's, here's, where's, when's, why's, how's, who's, what's, and that's.
Some scholars claim that E-Prime can clarify thinking and strengthen writing, while others doubt its utility.
