Usage Note: Traditional grammar requires the subjective form of the pronoun in the predicate of the verb be: It is I (not me), That must be they (not them), and so forth. The rule is based on the vague notion that the complement of be is being equated with the subject of the sentence and so it should be treated like the subject and have subjective case. This reasoning is faulty because the grammatical case of a noun or pronoun is really determined by its position in the sentence, not by what it refers to, and in anything but the most formal style the complement of be takes objective case: people say It's me, not It's I. Indeed, in informal contexts the subjective pronoun can sound pretentious and even ridiculous, especially when the pronoun also functions as the object of a verb or preposition in the relative clause, as in It isn't them/they that we have in mind, where the third-person pronoun serves as both the complement of is and the object of have. In our 2016 survey, 71 percent of the Usage Panel accepted It isn't them that we have in mind, while only 53 percent accepted It isn't they that we have in mind. Following the traditional rule in such cases is more of a stylistic preference than a grammatical imperative. Fortunately, writers who wish to avoid sounding stilted but prefer not to violate the standard rule can usually revise their sentences easily enough: They are not the ones we have in mind, We have someone else in mind, and so on. See Usage Notes at I1, we.

Our Living Language In place of the inflected forms of be, such as is and are, used in Standard English, African American Vernacular English (AAVE) and some varieties of Southern American English may use zero copula, as in He working, or an invariant be, as in He be working, instead of the Standard English He is working. As an identifying feature of the vernacular of many African Americans, invariant be has been frequently seized on by writers and commentators trying to imitate or parody black speech. However, most imitators use it simply as a substitute for is, as in John be sitting in that chair now, without realizing that within AAVE, invariant be is used primarily for habitual or extended actions set in the present. Among African Americans the form is most commonly used by working-class speakers and young persons. Since the 1980s, younger speakers have tended to restrict the use of the form to progressive verb forms (as in He be walking), whereas their parents also use it with adjectives (as in He be nice) and expressions referring to a location (as in He be at home). Younger speakers also use invariant be more exclusively to indicate habitual action, whereas older speakers more commonly omit be forms (as in He walking) or use present tense verb forms (such as He walks), sometimes with adverbs like often or usually, to indicate habituality. · The source of invariant habitual be in AAVE is still disputed. Some linguists suggest that it represents influence from finite be in the 17th- to 19th-century English of British settlers, especially those from the southwest of England. Other linguists feel that contemporaneous Irish or Scotch-Irish immigrants may have played a larger role, since their dialects mark habitual verb forms with be and do be, as in “They be shooting and fishing out at the Forestry Lakes” (archival recordings of the Royal Irish Academy) and “Up half the night he does be” (James Joyce). But some have argued that the development of invariant be in Irish English came after its development in AAVE. Other linguists believe that habitual be in AAVE may have evolved from the habitual does be construction brought to America by Caribbean Creole slaves and migrants from the 17th century on; until very recently, the construction was still in use among Gullah speakers from coastal South Carolina and Georgia, where Barbadian and other Caribbean slaves had been well-represented in the founding populations. Still other linguists suggest that invariant be is an innovation within AAVE arising in the second half of the 20th century, essentially a response to the wide range of meanings that the English progressive tense can express.
