What does dost mean?
"Dost" is an archaic verb form: the second-person singular present of "do," reserved historically for addressing one person familiarly with the pronoun "thou." A sentence such as "What dost thou want?" corresponds exactly to modern "What do you want?" The form was standard in Middle and Early Modern English and survives most vividly in the King James Bible and the plays of Shakespeare, which keeps it recognizable even though everyday speech abandoned it centuries ago alongside the rest of the "thou" system. Today "dost" appears almost exclusively in deliberately old-fashioned writing, religious quotation, poetry, comedy, or fantasy dialogue that imitates historical speech. Because its use depends entirely on agreement with "thou," it cannot be paired with modern pronouns like "you"; doing so produces an error rather than a stylistic flourish. Knowing "dost" helps readers navigate classic literature fluently and lets writers evoke an antique register with a single well-placed word.

Etymology of dost
Dost descends from Old English "dēst" (later "dyrst"), the second-person singular present of the verb "don" (to do), which traces back through Proto-Germanic *dōną to the Proto-Indo-European root *dheh₁-, meaning "to put" or "to set." This same ancient root gave English not only "do," "did," and "done" but also "deed" and "indeed." As English lost the distinct singular-plural pronoun system during the Early Modern period, "thou dost" gave way to "you do," leaving "dost" as a fossil of an older grammar preserved chiefly in scripture and literature.
How dost is actually used
Strictly archaic: "dost" belongs to Early Modern English and is found in the King James Bible, Shakespeare, and literary pastiche. Modern speakers use "do" with "you" instead. Using "dost" today is deliberately archaic or humorous, and it must agree with "thou" — pairing it with "you" is ungrammatical.
