  3. 3
    same actionverbauxiliary
    Used in place of a verb already mentioned so it need not be repeated, but not normally for be.

    I play tennis, and she does too.

    They enjoy the theater as much as we do.

    UsageStands for an earlier verb: I play tennis, and so does she; after be, repeat be: so is she.

    Note

    A stand-in for a whole verb phrase, not just a verb: in I play tennis; she does too, the word does replaces play tennis. Most varieties of English keep it away from be and the other auxiliaries, but African American Vernacular English can use it there, as in they don't think it be like it is, but it do. Fronting the rest and ending on the pro-verb, likes her cappuccino, Mary does, is a colloquial British pattern.

Origins

Meanings 1–26, 28–31

From Middle English don, from Old English dōn, from Proto-Germanic *dōną, ultimately from the Proto-Indo-European root *dʰeh₁- ("to put, place, do, make"). Its many relatives include the doublets deed, deem, and -dom, and, through other languages, words like feast, theme, and thesis. Some linguists think the meaningless use of "do" in questions and negatives ("Do you like it?") may be a Brittonicism calqued from Brythonic.

Meaning 27

Traditionally credited to the Italian musicologist Giovanni Battista Doni in the 17th century, as an easier-to-sing revision of Guido of Arezzo's syllable "ut," taken from the first syllable of Latin Dominus ("The Lord"), with the justification that God is the tonic and root of the world. Some also speculate it was an abbreviation of Doni's own name.
